Of course a person has to have some sort of opinion of it under such conditions, but is it going to come down mostly condemning the weapons enabling the aggressor or thankful for the weapons that enable some measure of violent defense?

The Slaughterbots campaign argued, rightly, I think, that advanced autonomous lethal weapons should be suppressed because they enable unethical uses and unscrupulous actors far more than legitimate defense.

It can't really be seen in isolation from the environment (social, economical, etc) it's going to come into I suppose, but in the real, concrete world we have creating them is not a neutral act, and some of the consequences are reasonably predictable.

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.
