If you offer empathy to someone in an angry state it will help them feel seen heard and connected to you. But if you offer that empathy to someone in an angry state who has abusive mentalities... It won't work.
Someone who relates to other people through power and control, or an abusive mindset, uses anger to justify intentionally hurting others.
Anger is a valid thing in all healthy relationships. But using your anger to justify harmful behavior is abusive and not ok.
