No it's not. It is unacceptable in all cases. I don't understand how otherwise principled "all humans are humans and deserve rights" people are suddenly a-OK with rape or torture if it's someone they've decided is a "bad person" without realizing they're doing the exact same thing fascists do to justify human rights violations, but it's a pathological problem. If you think it's ok for you (or anyone) to decide who is allowed to have human rights and who isn't, you're an authoritarian in denial and you will fall victim to the next authoritarian leader who agrees with you about who we're allowed to torture.
