One is answerable with fact. The other is unanswerable with anything but subjective opinion, and inevitably drags the ensuing thread into pointless back-and-forth over, in this case, particularly well-trodden ground.
And here we go over the well-trodden ground yet again. "Should" according to who? You? See the problem there? It's perfectly possible for other people to have equally valid moral positions as you while taking a different stance on this specific question.
Trying to dictate morality never ends well. Especially in cases like this, where the specific tech is not only possible, but also has unarguably legitimate uses, and is therefore pretty much inevitable. You just end up tilting at windmills, and the ensuing hot air back and forth just creates pointless noise, generally adding little to the discussion.
