Funny you mention crossbows; the Church at one point in time tried to ban them because they democratized violence to a truly trivial degree. They were the nuclear bombs and assault rifles of medieval times.

Also, I will take this moment to also mention that the "problem" with weapons always seem to be how quickly they can kill rather than the killing itself. Kind of takes away from the discussion once that is realized.
