Deontology - Who/what decided universal laws were moral? Who/what decided what morality was in the first place to base laws on?

Consequentialism - Who/what decided that consequences, and which ones, were good/bad? If telling a lie would save person's life consequentialism says that it's the right thing to do. But what if that person you saved had murdered someone? What if you knew they had? Would it matter either way? If it wouldn't matter either way then how can you determine whether it was the right thing or not? If it would... well who/what decided that it would?

Virtue Ethics - Who/what decided what is virtuous or not? Who/what decided to attribute virtue as a positive character quality?

¯\_(ツ)_/¯ 

 Yes. Morality based on immorality is what I see today.
