Not that I have a stake in this argument, but it should be noted that Tommy Gioeli was remorseful decades later after the accidental killing of a nun. This is even though he wasn't involved in the actual hit team, but was in a crash car down the road.
I didn't hear about that but if it's a case of someone claiming remorse in order to get leniency then I wouldn't be taking a conman's word at face value. And if you are driving the crash car - in any kind of crime - I would've thought that makes you part of the hit team/bank robbing team. You're deeply implicated.
