I think there are some instances where it's definitely bad. E.g. weapons that, if used, can by themselves extinguish humanity. Most instances are not that clear unfortunately - lots of sides to the story, extenuating circumstances, etc. etc.

It's not an easy question. However, as the creator of the software I guess I feel that my opinion should count in how it's used. As a simplistic example, if in some dystopian timeline my OSS were used to facilitate a holocaust I'd like to be able to do something to halt that. It doesn't matter that the perpetrators feel that what they're doing is right.
