Charles Bronson loved it, whereas Robert Forster didn't...

One memory I have of Vigilante is that when Forster used violence as a last resort, he didn't look as if he was enjoying himself at all. He looked as if he was emotionally dead, thus neither enjoying nor demonizing his own actions, whereas in Death Wish 1-3 (the only ones I've seen), Bronson looked as if he was finding more relish in killing the bad guys. Just witness him pumping the drug dealer full of bullets in Death Wish 2 during the park shootout. Yet, in one DW2 scene, when the TV's on and it shows the killings that he's commited, Bronson switches it off.

I guess this shows that Bronson, too, hates what he's doing, but has to do it, the Old Testament way. Forster's the same, too, but not quite as sadistic, although he must have felt some relish in throwing his son's killer off the tower.
