I was going to say my dad, but after reading the rest of your stories, he seems pretty tame.
I have a sister who has completely written him off...he drinks, piddles away his money on crap, and then winds up having to borrow from other family members. At least he used to borrow, anyone who could lend him money now refuses or won't speak to him!
Now its mostly the drinking that gets to me...he came over the other day, had been drinking, and proceeds to lay on my floor.
Not to mention when he told my DH that he was thinking about leaving my mother.

They've been married for 32 years now.
To top it all off he is a pervert, has to comment on any woman who walks by, even takes pictures of random women on the street if he happens to have his camera!
There were mony thingsg that happened when I was a kid that have colored my opinion of him. Now it's hard for me to be comfortable around him at all. But again, he sounds tame compared to some of your stories.
