Wolverine can quickly heal from pretty much any wound, an ability he shares with Marvel Comics character/4chan personification Deadpool. In the comics, Deadpool undergoes an experimental procedure that "implants" him with Wolverine's healing factor, which leaves Deadpool both ugly and insane ... but hey, it works! There are some kinks to be ironed out, sure, but why isn't this a bigger deal? At the very least, studying Wolverine's cells could help cure diseases and advance medical science. We know this because there's actually something like that in the real world: HeLa cells, named for Henrietta Lacks, the woman they were found in.

If you observe from the right angle they even look like they have Wolverine's hair.
HeLa cells are "immortal," in the sense that they don't die after leaving the human body. Since they were discovered in the '50s, they've been used in developing vaccines, cloning, gene mapping, in vitro fertilization, and have even been shot into space, because sometimes even Science gets bored. Now imagine what we could do with cells that are actually immortal, not just technically. Annoyances like broken bones, the common cold, or even death would become a thing of the past. If Wolverine is committed to the greater good, he'll stop using those hands to stab ninjas and start using them to jerk off into a cup.
He's the best there is at what he does, and what he does gets exhausting
after the third or fourth time in a day.
