I'm not saying that he didn't have any influence in bettering society! Just that there is a vast gulf in what the two men did, and what they set out to do.

"I shot a shithead in the hopes of discouraging other shitheads from being shitheads" if successful, is a positive - including in shaking up some potential shitheads into being less shitty for a time. But it doesn't change the game itself.
