Storm feels moral responsibility when she kills. Psylocke, being a telepath, likely feels every murder she commits with her psi-knife.
And Archangel's Death persona is shown to be unwell, and eventually went completely evil and had to be killed by Psylocke, another action that deeply hurt her.
Death with consequences, that means something, makes for more mature comics than senseless gorefests.
