The 4 Evils were all different people. The way they thought about life and the way they reacted to external stimuli were different.
Wrath was more suited for his namesake than any of the rest. His immediate reaction was rage. He directed his anger at anything he could find until he could stop thinking about the things he didn't want to think about.
Lust was more reserved. Despite her title, she was not such a person. Rather, she isolated herself from the world when she needed to cope with something. It would become hard to see her until she'd found some peace.
Gluttony was strange. He never seemed to show any emotion, but there was definitely something going on in his head.
Nobody could understand him, but Envy could see that there was something going on in his mind.
And as for Envy herself…she overcorrected in a sense. Her entire desire for chaos was overthrown by a desire for peace, and anything related to her old life made her weaker.
