Yes, I think it is bad. We don't encourage people to bang their heads, bite their tongues, or otherwise deliberately hurt themselves, nor do we encourage people to engage in destructive behaviors such as self-starvation or abuse of chemicals. Why on earth would self-harm be any different? (this is rhetorical)

I will back off here as I have no personal experiences with self harm and therefore cannot offer anything but my own emotional reactions to such behavior.
