I think it's clear that Stan Lee's favorite plot was the guy who repents at the last minute, and then dies. He did this so many times with so many different artists, sometimes even with the same lines.
The most famous story of this type, of course, is "This Man, This Monster" (Fantastic Four #51) where an anonymous bad guy switches places with Ben Grimm and then winds up sacrificing himself to save Reed.
But Stan had used the same line about dying like a man when Betty Brant's criminal brother got killed trying to protect her from gunfire.
And there was also Simon Williams in Avengers #9, who became Wonder Man, attacked the Avengers, and then sacrificed his life to save them. And that was the last time we were ever supposed to see him, ha ha ha.
