But to your point Oxymoronic" describes something that uses or embodies an oxymoron, which is a figure of speech combining two contradictory words (like "deafening silence," "sweet sorrow," or "living dead") to create a new, paradoxical meaning, revealing deeper truths or complex emotions, often for rhetorical effect. It points to self-contradictory ideas, qualities, or phrases, highlighting inherent paradoxes in language or life, such as "ethical banking" or "honest politician".

Because you have to look at the full picture before judging the person. Which is why I choose to not judge the person and limit my judgement to actions and behaviors. It's easy for me to say this or that action were good or bad. It's a little harder for me to say this person or that person is good or bad because I don't have perfect information to make that call.
