Just to quote the FAQ by wobnam (I added the bold) from the main thread as to what happens if you kill your own character or give someone permission to kill your character.

I ALREADY SIGNED UP; CAN I CREATE A NEW CHARACTER? You can only have one active character at a time. If you want to create a new character to replace the one you already have, you can, but: - your new character must be in the same faction as your old one. - your old character dies. Feel free to end his story in a MOC. - your personal score points are lost, your new character starts at 0 personal points (faction points are not affected). - you can only switch once every four months.
