Morphine nuts need a nerf.

I feel like knee jerk tends to carry this negative connotation.

There's a reason for that.

It tends to mean someone reacted immediately to something bad happening and, instead of going about it and thinking how they could prevent the bad thing from happening or even think of if it's a necessary bad thing that could feel less terrible, they went for the most obvious part of the bad thing and said that that is the problem.

A carefully thought out response after tripping a claymore mine in a game would be to see if there was another way around to where the person was trying to go, or to try to find similar mines while they're playing from then on.  A kneejerk reaction is to say the mine is bullshit and should be removed.
