I think you're right and it's possible to have something that exists with no other purpose than to cause harm. And it's not moral to make that thing. I also don't think it's fruitful to find the specific circumstances it's moral to eat babies (go down philosophical rabbit holes until you find the one time that doing something despicably immoral is actually the moral thing to do). But I would say the technology is the least important part of the problem. A moral person uses dangerous tools sparingly and intentionally harmful tools never. If Palantir did not exist, would they perform the raids? I think so.
