I agree that this is better to have no arrest for crime thought, no censorship, and no (government covered mass) murder.

It doesn't mean that we are objective on this regard. On the contrary, at least for me, it comes from the subjective feeling that as I dislike the sentiment of being oppressed and I do feel empathy for other people, I wish them not to be oppressed either. This is all subjectivly grounded, and it's fine - to my mind at least.

Let's not pretend that something is objective just because it's deeply rooted into the best part of our hearts.
