How can a horrible person gets away with child abuse & enjoy a life in the sun with a new family???

My stepfather now has a Facebook profile.... Not that I'm going and checking the search engine for him.... But, I saw it on my brother's friend's list. Lovely!!!! I shouldn't have clicked on his photo... But, I did!!!! He has a huge house, 3 full blooded boxer dogs, a cat, two boats, a his and her workshop with a.c, they have parties all the time..... Lake trips.... How can someone that did what he did be enjoying a perfect life with his new wife of 6yrs.... Yet he left my mom with a house payment, his truck bill of $27,000 of his repo vehicle she is still paying on.... He gets to drink a budwiser on a boat. Makes me so sick!!!!! He should be in jail. Life is so unfair I don't get it. I don't understand... And why does my stupid brother have him on his profile so, now I see this dirty man's face all the time or read his comments to my brother.... So upsetting!!!!!
