[ Berserker's narrow focus can seem extremely cruel. It's weird to think that this is the way he shows concern. Not that this in particular is concern, more of a retaliation for what he saw as disrespect. To lay bare someone's weaknesses, to make sure they won't become a problem for himself later. ]

Trying isn't enough. If you lack killer instinct, you're a liability to everyone around you. I can smell the weakness in you...It will come to harm you or someone you care about sooner or later.

[ Again, without judgement, as if these are facts on display before him. ]
