Yeah that's pretty understandable and happens IRL. If I include her the fan wiki puts his kill count at 24 total including zombies. Joel had been surviving in the apocalypse for 20 years by the time the main story begins and he kills in the hundreds just during the course of the game. Lee's part of the games takes place over a few months. Based on the wiki Lee dies at 105 days into the apocalypse, which is right before Rick's group find Woodbury and the Governor in the comics and during the time skip between seasons 2 and 3 of the show for reference.
Also technically speaking Lee jobs to a random zombie,
so that's a pretty major anti-feat if we're doing a who would win here.
Lee's obviously a more interesting character though, and his game is much less schlocky and actually broke ground.
