**Bronson should have shown restraint.**
**CONTAINS SPOILERS**
To be fair, the bad guy did warn Bronson that he would kill the girl - but Bronson did not listen. He kept on coming at the other guy until the guy delivered his promise and killed the girl. Bronson pushed the guy into it. He _did_ warn Bronson. Here is the unacceptable part - _Bronson then mercilessly blows him to pieces._
The man was trying to reason with Bronson and gave him ample warning but Bronson just opted for a violent conclusion. Bronson should have not killed the man - especially as the guy was trying to make concessions for Brosnan.
Bronson brought it on himself.
"Death Wish 4: The Crackdown" really ought to have a more routine and listless quality about it by this late date and while there is a faint sense of that detectable here it isn't as prevalent as it could have been. The film pushes incredibly hard to create some sort of new and innovative angle on its central theme - a theme which has now gone from being highly controversial and politically and socially divisive to becoming acceptable and commonplace action movie fodder in just a span of fifteen years - to trigger the mayhem and by and large this results in a much better film than you could have ever expected. There is still an abundance of gunplay on display, but fortunately the unpalatable and lurid violence towards women (which still exists here to a certain extent) receives far less attention from screenwriter Gail Morgan Hickman than some of her male counterparts in previous times and best of all there are no deliberately cruel and horrifically over extended rape scenes to fast forward through this time around.
