So your going to torture and slaughter animals, take the food from starving people grew, ruin your body and destroy our planet just so you can consume som disgusting rotting flesh that will clog up your stomach?? Really?!?
In many cases of self-harming, it is because the person feels that they are in control when they harm themselves. Outside forces often times control our lives. Bosses, money, parents, friends… They all have some kind of effect on us, and if it's negative, some feel that cutting themselves or harming themselves puts them in control of the pain, when really, there's no control to be had at all.
