If the person is
in the act that imminently threatens the lives of innocent others and if you are one of the innocent “others” then you may use force, even lethal force to defend your life. No need to call Dr. Phil in for a sit-down with the aggressor. The aggressor is defined by his/her act, not the intention.
I write
in the act as one may not act preemptively against a perceived threat. Nor may one kill an innocent whose threat is real but only so because he/she exists. To wit:

In this very special instance, Jewish law steps in and calls the baby an aggressor albeit an unintentional one.
I came to make this exact distinction. This also provides us with an ethical framework upon which to judge the morality of preemptively killing a person with a fatally communicable disease: it is immoral to do so, even if the fatality rate were 100% because in such a case you aren’t
reacting to the reasonably understood lethal threat of the aggressor’s
action, instead you’re doing so to their mere existence.
I’d argue this extends even to cases in which the threatening individual engages in some kind of behavior (not mere existence) that only
circumstantially causes a lethal threat and that person is not reasonably expected to understand the lethal nature of such circumstances. Using this framework an
aggressor is one who is a lethal threat
through aggressive behavior, regardless of their individual understanding of the behavior.
In this way otherwise mundane and
amoral actions do not warrant a lethal response simply because bizarre or atypical circumstances render such actions indirectly lethal.
