There is always a bigger fish
This my reflection after Richard's meeting with Red. In episode 5 we see him smoking under "no smoking" sign, threatening young lady to rape her.
In episode 6 we see him again. He tries to be tough ("don't call me kid") but he ends up standing scared, almost in tears.
After this meeting he is broken, not so tough anymore, shouthing threats, driving furiously and killing a child on pedestrian crossing. In fact he acts like a kid who was bullied at school.
Does he want revenge? Surely. Can he deliver? I'm not sure.
