I voted for 'no way'.

Clark (in any Universe) has too much respect for life in general to ever end a life - even his own. IMHO, it just isn't in his make up at all. Getting addicted, okay, but suicide?

That said, I can believe he'd consider it, for a moment, if he was really, really desperate. sad

I'd be curious to know how a writer would pull this off. Clark is invulnerable; how would he do it?? Even for humans it's not so easy. Yuck!! Just thinking about it makes my skin crawl. The solutions we humans pick clearly wouldn't work for Clark. I mean, he couldn't throw himself before a train, now could he?

The only thing I can come up with is flying towards the sun and getting burned to a crisp.

Again: Yuck!!!

Lois: Well, I like my quirks. I think they make me unique.
Clark: You certainly are unique.

Clark: You're high maintenance, you know that?
Lois: But I'm worth it!
