Some questions after my first MG mission

In case it hasn’t been explicitly stated, #1 is correct. #2 isn’t necessarily. I think it’s perfectly fine to shoot for a PC death in the first major conflict! Life’s hard in the Guard, and in any case it’s not easy to completely murder someone in Mouse Guard.

What you have to realize is that if your opponent sets a goal that you cannot abide, the only way to ensure it doesn’t happen is to win without tying. That’s the reason why it’s not worthwhile to script incompatible goals, because by winning you already deny your opponent his goal. The only way to deny your opponent his goal is to win yourself, not to set a goal counter to his.
