Survivors have zero respect for the killer
And no I don't mean it as a "Wahh they are so mean! they tick the flashlight and teabag!".
I mean they have zero fear, zero worries, you're literally aproaching them wtih the intention of killing them and they won't care. You can approach them while they are doing a gen and they will just laugh it off and keep doing it, specially if they are about to finish it, after all, why would they even worry when they can just use one of the 9999 pallets near them if you hit them or if you hook them someone will just unhook them.
Killers are as scary and threatening in the game as a flower. Hell Survivors will even keep doing gens with no worries even while having deep wounds.
