Walter has a lot of good points there... and if Wrath had reached the point in his life where he questioned everything, it would have provided him with some serious food for thought.

BUT... he never got that far, and right now he thinks he's got everything figured out.

So his answer is matter-of-fact, and nonchalant.

"I'm not a people. I do what I want."

He obviously doesn't need a reason to like somebody, psh. That's clearly a human thing.
