It's a bit of a weird one for me; Because it depends; If it's for a legitimate reason like you have major problems within your life, Then i suppose it's their way of coping, but if it's over your boyfriend braking up with you or something stupid, or they post their cuts on Facebook or their scars, then to me you are the biggest knob on earth; Their are people out their who have worse problems than you and they don't cut themselves, but i suppose people cope with things differently.
