Death Match

[Alcon]

This is one of those issues that almost amuses me with its idiocy, until I realize I fall on the sides of idiots.

If two people want to sign documentation to say the other one has permission to take the other one's life and vice-versa, what should I do about it? If someone who is mentally stable (perhaps a stretch under the circumstances, but go with me here) would not mind losing their life in the pursuit of fighting someone else, why should I care?

This is, I would hope, not an issue that comes up very often. And if legal, it should at least require a legal agreement beforehand. If someone just says "he challenged me to a death match on the spot, I swear!", I do not think that constitutes sufficient reasonable doubt.
This is one of the issues that I do not care about, in all honesty, but if it came down to it, I'd have to vote to legalize them.
