Morally, no, I don't believe there are cases where it's moral. Justified, however, that all depends on personal beliefs. I believe there are rare cases where it's justified...id est mass murderers, child rapists and such.

However, that still doesn't mean it's moral, even to a person who may find it justified.

Personally, I don't believe that Morality and Justification should be paired with each other to begin with.
