I think self hate has a lot to do with low self-esteem, before someone can hit himself or herself there must be something that must attribute to eat which might cause such situation, self-hate is actually a gateway to depression which might lead to suicide if care is not taken and if urgent action is not taken too. Self-hate might be as a reason of bad peer group, let me give an instance by what I mean by bad peer group, when a young boy can't use the type of phone his friends use which might lead to them saying all sorts of bad things to him like "your parents are poor" and in turn this might lead the person to hate everything about himself that is where self heat comes in and with this it can proceed to depression and then suicide, self-hate is very bad and dangerous not just only to our health but also our future.
