Yes. Him being a pussy makes it more believable, not less, because weak, pathetic cowards are more likely to lash out at anyone they perceive as weaker than them. Weakness mixed with narcissism and low impulse control is a HUGE red flag for violence, because they seethe over their inadequacy and want to hurt people. Look at every single school shooter: not a single alpha male. They're all giant cowardly faggot losers.
If you want a lolcow example, look at Ethan Ralph: When confronted by a man, he denies his own name in fear, but there's audio of him beating and threatening to kill his wife, because his wife was weaker and smaller and he could unleash his pathetic, impotent rage out on her.
I'll be honest: I would've been more surprised if we were given definitive proof that he NEVER hit his wife or kids. I don't know how anyone can watch the Keanu stream and NOT see red flags of a domestic abuser.
