To technically be your ancestor's judge would violate the laws of space and time. Remember that.
Report the facts on your ancestor as clearly and as accurately as you possibly can. Let the information you locate determine the conclusions you reach about your ancestor. There are many reasons to leave the judgments to someone else, but the biggest one is that we, as genealogists, rarely know the whole story.
The only information we have is what got recorded and we only have that recorded information which was preserved. And that often is a fragment of the reality.
