If there's still any kind of debate over this,
Claim: Objects cannot be evil.
The distinction between good and bad is a moral one, morality presupposes a consciousness and freedom of choice.
Where there is no choice, there can be no 'good' and 'bad', or 'right' and 'wrong'. You are literally unable to choose between either, which voids your morality, as your hands have been forced to act (lack of alternative). This applies to some human actions, but mostly, to non-human things, such to include: inanimate objects. For an object to be moral, it must have the capacity for rational decisionmaking (first and foremost, between 'moral' and 'immoral'), which it doesn't possess.

You don't, because they cannot be held responsible for their actions, they have no choice but to act in one way, and one way only.
You would be merely sanctioning the actions of an arson, or freak that tossed you in the ocean, or the burglar that shot you, if you were to do that.
