Rule of dealing with enemies that you can't take care of alone
Rule 1: don't go to your enemies to deal with your enemies
Rule 2: If you break rule 1 atleast make sure that the one you are seeking help from isn't enthralled by, loyal to, or obsessed with the one you are trying to destroy.
Rule 3: If you break rules 1 and 2 you might as well hang yourself over a den of lions with a nuclear bomb about to go off because you are already trying to kill yourself
