forget if im wrong but i dont remeber Gambit having a tortured past i got pretty much every appearance by Gambit i comics and he seems normal, i think the only thing thats been hard for him to go thru was losing his wife BellaDonna but aside from hat his past have been pretty normal of course we all make mistakes like when he worked for Mr.Sinister and Mr.S send the Marauders to kill all the Morlocks(Mutant Massacre) but everyone make mistakes!
