Red Superfly, I agree with most of your points, but I don't agree with you when say that nobody can truly kill Wolverine.
That's absolutely not true. These are some ways to kill Wolverine:
1. You can strangle him
2. You can drown him
3. you can rip out his heart. Granted, it won't be easy with the adamantium skeleton in the way, but it can be done.
4. you can throw him out in space - no air there
5. you can poison him - he is resistant to most poisons, even the deadly ones, but I'm quite certain a special poison can be made
6. you can wound him so badly (doesn't matter where) that he loses too much blood. That's the most realistic way to kill Wolvie, I think.
7. throwing him in a volcano might also work
Don't get me wrong, I love Wolverine and I don't want to see him dead, but nobody ever said that he was immortal, cause he isn't. He ages very slowly, and heals extremely quickly, but can be killed. His healing system is both wonderful and unique, but it isn't so that it is able to cope with every kind of injury.
See you.
