This is the fundamental argument that is going on on many threads. Hypothetical Situation: 3 People in the H-World. You, Person X, and Frenchguy. You know nothing about Person X. The following information is given: You have the first move. Person X has the second move. French Guy is a sideliner. If you do anything except for killing Person X, Person X, on his turn will have a 50% chance of killing you - and he will only attempt to kill you. Therefore, if you do anything except for killing Person X, you have a 50% chance of being killed yourself. In the event that you do anything except killing Person X, the Frenchguy will remain unmoved. If you get killed by Person X on his move, the Frenchguy may be swayed a tiny bit towards the Person X side. If you Kill Person X: He has no chance of killing you. You have 1--% chance of surviving Person X. In this situation the Frenchguy will be very upset at you. This is a SUBJECTIVE question, not an objective. Put youself in the shoes of YOU. What would you pick. Oh - there are no other choices: disabling, freezing, arresting or anything else you can come up with, means: not killing. Therefore, the same death percentages apply. Also, you can't reason, explain, persuade, hypnotize the Person X. You can also do whatever you want with the Frenchguy at any time.
