I think Bronson's line is a toss up with Eastwood's line from Unforgiven. Eastwood's character William Munny just shoots one of Gene Hackman's men and Gene Hackman complains that he just shot an unarmed man and Eastwood replying says, " he should have armed himself." Kind of foreshadowing for what's going to happen to Hackman's character. Either way both are on top as the best Western actors of all time
