These new persona weapon traits are some nice idea's but i allways remind me at the intelligent and philosophically capable "Exponential Thermostellar Bombs" from John Carpenter's sci-fi film Dark Star.
But compared to the bomb who is/was/willbe realy hot to explode, i am geting many weapons with "Kill sorrow" trait which hate it to kill.
The special weapon for a pyramanic pacifist ! :-)
Which weaponsmith realy create such weapon, i don't think any potential buyer would like a weapon with that withdraw.
So i think the AI got some mental shock from the last owners dead, and just don't want kill/fight anymore to fear that the new owner will die too.
