I like that Komaeda is comfortable with talking about his true feelings when it comes to Hinata, and allow himself to be a bit annoyed by him. It's so much natural than how he acts with anyone. It really shows that they're friends.
I also believe he genuinely thought Hinata was risking his life trying to befriend him and who can blame? I don't even think he meant to sound insulting.
"He's an odd one. He has no talent (power) so even if he has courage (to face my luck) his actions were reckless (because he could get greatly hurt)"
Him going, yeah we are friends :D kinda proves my point. He really was talking with slight teasing and genuine concern in his heart
