Alright, so we got this immortal guy, he pretty much eats and breathes "living forever sucks"
So after being alive for centuries he decides to off himself.
Problem is, aside from not aging, his body regenerates from any injury instantly
So he decides to toss himself into a Volcano, in hopes that if he's boiled to nothing he will cease to be.
However, this is not the case, he is instantly boiled then regenerated just as quickly.
However this leaves him the problem of being stuck in a effin volcano.
So basically my question to you is...what is the practicality of clawing your way out of a valcano assuming you had a healing factor strong enough to regenerate the...ya know...lighting on fire and melting and crap?
