In my opinion, he should have died after being run over by the train. He is such a despicable character, but he can't pull it off because he lacks the appeal that the other villains have. He just feels like a desperate baby who gets what he wants because he inherited the power of the family.
The only satisfying part of his other boss battles is the melee prompt where Ada punches the stuffing out of him.
this guy couldn't have been more annoying even if he tried... at the point when the fight on the bridge happened I was hoping he'd stay down... nope... after the rocket launcher, it felt satisfying to finally put him down.
