Why do most people hate Richter in Nocturne?

Look, I genuinely want to know what went through some peoples' heads when watched the series, like they they took one look and said "Man, this Richter's a bitch." I'm at the point where trying to understand why they think this that it's starting to piss me off, like I'm pacing around and having fake arguments. I can understand if someone thinks that Nocturne isn't written well, and I know damn well that it ain't perfect, but why the fuck are people calling Richter calling him a pants-shiting cry baby when he literally watched his mother be MURDERED in front of him and had a panic attack when saw the bastard who killed her? (No offense to Olrox fans) Please help me.
