Deacon was obsessed with Amber - in that vein, it would make sense that he would want to get rid of Daniel -- see full story of deacon below:
In an eleventh hour move to stop Amber and CJ's wedding in October 2000, Rick tracked down the biological father of "little Eric" in order for him to sign over parental rights to him and Amber. Rick offered Deacon $100,000 for full custody rights to Eric III and he initially agreed. When Deacon faltered, Jonathan initiated a plan for the Forresters to force him into the deal. When Deacon discovered a bug and recording device, he took the papers and left the Forresters empty handed. The Spectras and Forresters started a bidding war for Little Eric. Deacon took the child to live with him and his girlfriend, Carmen, at his apartment above his club, The Lair. Deacon's attraction for Amber soon developed into much deeper feelings of affection. Carmen became suspicious of Amber's constant visits and Deacon's motive for not accepting the $1million offer. Carmen's jealousy intensified one night when she took Little Eric to the rooftop of Deacon's building. Amber confronted Carmen who hesitantly returned Eric to Deacon. The confrontation ensued, there was a struggle and Carmen fell to her death.
When Darryl, Deacon's father, paid Deacon a visit and left him battered and unconscious. Deacon vowed to be a better father than Daryl ever was as he continued to develop feelings for Little Eric. A legal arrangement outside of the Forrester family influence had Amber agree to a four month live-in arrangement with Deacon and Little Eric, at the end of which Deacon would relinquish all parental rights and let Amber walk away with Little Eric. Brooke's interference and convincing photographs of Rick and Amanda kissing at their interstate tennis match drove Amber into Deacons arms. A friendly kiss was interpreted by Rick as a reason to end his engagement to Amber. Deacon organized a surprise getaway for Amber to Las Vegas where they bonded. An encounter with Daryl led to a breakthrough for Deacon in overcoming his childhood demons. Stephanie informed Rick of Brooke's manipulation and searched for Amber. Rick and Amber soon reunited and planned to marry. Amber asked, and Deacon agreed, to sign papers releasing her from the four month agreement but allowing visitation to Little Eric. Eric, Stephanie, Brooke and Thorne visited Deacon at his club. He was furious when Eric boasted about not having to pay the $1million. Deacon ordered them out and promised that they would all pay for the abuse. Deacon soon developed a friendship with Bridget and both were unaware of who the other was until Bridget left Deacon her number revealing her as a Forrester. Deacon came clean and told her his name. Bridget was stunned when she realized who he was but Deacon manipulated her into thinking he cared for her. Before moving ahead with his plan to use Bridget, Deacon tried to get Rick, Brooke and Amber to stop the wedding. When Amber and Rick's wedding began, Eric stood up and asked the minister to stop as he approached Deacon and demanded he leave immediately. Eric and Brooke were mortified when Bridget announced that Deacon was her date!
The guests were asked to leave and Deacon and Amber went to the den to talk while the rest of the Forresters tried to make Bridget see Deacon's true intentions. When Rick, Eric and Brooke entered the den, Deacon forced them to choose between Amber and Bridget stating he would be leaving with one of them. Eric, Ridge and Thorne beat Deacon before throwing him out of the Forrester mansion. Bridget ran after him. In the car, Deacon proposed, they drove to Las Vegas and got married. The Forresters were shocked and appalled when they learned of Bridget's marriage and resolved the situation temporarily by letting the newlyweds stay at Taylor's Beach house without any family interference. When Eric, Brooke and Rick called Deacon on the speaker phone demanding Bridget be sent home, Deacon retaliated by leaving the phone off the hook as he made love to Bridget. The following day, Deacon has hit by a car as he exited Insomnia. At the hospital, Bridget's faith in Deacon was strengthened when he chose not to press charges against the driver who hit him - Eric.
Deacon showed guilt over his actions related to Bridget but felt it was necessary to get Amber and "Little D" back. Bridget was devastated when she overheard Deacon admit to Amber that their marriage was a farce. Bridget confronted Deacon after Amber left and drove off, humiliated. When Deacon followed her, Bridget slammed her foot on the accelerator and lost control of the car. Deacon watched helplessly as she swerved off the road. While Bidget was unconscious and still recovering from surgery, Deacon realized he did have feelings for Bridget. Deacon admitted he didn't realize how important Bridget was to him until the accident occurred and wanted to make their marriage a real one.
Despite hesitation and pressure from her family, Bridget decided to give their marriage a second chance. After Brooke insisted that Amber and Deacon discuss their feelings with one another, the two of them agreed to part ways and make their respective marriages work. Little Eric broke into a fever and brought Amber and Deacon together. They shared a passionate kiss. When Amber learned she was pregnant with Rick's baby, Deacon confessed his love. Deacon went home and told Bridget not to worry about her birth control and fantasized about making love to Amber. Brooke begged Deacon to divorce Bridget. After some faltering, Deacon began to feel that he was holding Bridget back and agreed to leave her. As they discussed stupid things they had done in the name of love, Brooke and Deacon gave in to their attraction for each other and made love.
At Big Bear, Deacon asked Bridget for a divorce. He confessed to her that he slept with someone else, but he still loved her. Bridget stood by her man and gave him another chance. At Tony and Kristen's wedding, Brooke felt ill and a pregnancy test confirmed her condition. Upon learning she was pregnant, Brooke didn't tell anyone and went to a spa while Deacon stayed in LA with his wife. Deacon helped Rick save Brooke's company from being taken over by Ridge. Brooke rewarded Deacon with the job of Head of Promotions at Forrester. After news of Brooke's pregnancy came out, Whip Jones, the man who would have had Deacon's promotion, claimed to be the father and started blackmailing Brooke. Deacon became furious when Whip tried to seduce her away from him. Deacon continued his affair with Brooke off-and-on for months. Brooke couldn't take the guilt and moved to Paris with Whip so she would be able to fight her urge to be with Deacon. Deacon went to Paris after a disturbing phone call from Whip and again slept with Brooke. Feeling so horrible about hurting her daughter again, Brooke accepted a proposal from Whip, assuming her affair with Deacon would end.
Deacon married Macy in 2003, and the two raised Little Eric together. Macy died in a tragic accident not long thereafter, and Deacon was left to raise his son alone. He tried to get his ex-wife, Bridget, back, but she was committed to Oscar Marone. Not long after, Deacon began an affair with Jackie Marone. When Massimo had a stroke, Deacon delighted in tormenting him by telling him about the affair with Jackie, even drugging Jackie with Massimo fully aware. Massimo recovered but Jackie stayed with Deacon. Shortly after Heather Engle came to work for Deacon, he started having the old craving for liquor, not realizing that Heather was in league with Massimo to get revenge on Deacon. After realizing he couldn't stop the thirst, Deacon left Los Angeles to get his life back together, leaving Jackie behind.
I have to say that EVERY SINGLE STORY LINE is rediculous and way off kilter. And they go on and on and on just like the energizer bunny.
