You're not wrong, but Carol has always been a superwarrior killer. And she's been stupid quite often. You could probably make a whole megapost about Ms Marvel Super Fuck Ups.
It'd be nice if Marvel started separating the torturing, murdering, assassinating super agents from the helpful citizen heroes but in any case, Karla Sofen shouldn't be portrayed as a hero of any kind, or associated with the Kree warrior Marvel.
