If X does not wish to be killed, then X would try to avoid killing Y.

If Y tries to kill X anyway, then X would lack the reason to avoid killing Y. Therefore, if Y tries to kill X, then X would feel free to defend itself using deadly force until such time that the threat of being killed Y no longer exists.

Would Kantianism define this the correct behaviour?

The commutative rule defines a framework for other rules, but it would not define the whole system. Readers might have made this assumption, however.

Perhaps the above rules would better be described as part of game theory.
