For loving draws us more to things than knowing does, since good is found by going to the thing, whereas the true is found when the thing comes to us.
Thomas AquinasWithout doubt one is allowed to resist against the unjust aggressor to one's life, one's goods or one's physical integrity; sometimes, even 'til the aggressor's death... In fact, this act is aimed at preserving one's life or one's goods and to make the aggressor powerless. Thus, it is a good act, which is the right of the victim.
