When his core nature was questioned, he couldn't take it. So, his response was in the only way he knows, to whip his power and satisfy his ego.
When the other one was pushed to his deepest moral boundaries, he finds some strength to not do what's wrong. But, his desire (or weakness) to earn his kind of success breaks those boundaries.
People with a moral compass in the movie are few and far between. Out of them, one of them is weak, another is innocent. There's only one character with a strong sense of morality and strength. But the movie doesn't give us a satisfaction of a peaceful ending for that character.
Maybe, power wins a lot of short term battles with morality. But, at the end at least, would the war be won by morality?
It is anyone's guess.
