No, it won't. I know tons of people like that and they lead perfectly happy lives. They never get caught and if they do, they never feel any guilt or remorse bec they truly believe that the only important thing in life is pleasing themselves. If that is your MO, you have no guilt, no honor, and no remorse and so nothing that happens to you is your fault or something you deserved.
My MIL was one of them. When she died more than 300 people came to her funeral and were weeping and moaning about what a loss it was. We who knew her best were just agog at how well she had fooled so many people. The sickest one was this very nice little old Asian lady who was just sobbing. And we sat there knowing how my MIL had never referred to her by her real name in private, but always by a VERY derogatory racial slur. She did this even while she was dying after the lady would bring food over to the house. She was a witch up the end. And she had no regrets.
So, I wouldn't waste one atomic second of time feeling sorry for these horrible excuses of humanity. They would run you over without a second's thought.
