Things like this make sense.
People who do such monstrous things are not always monsters, they are, once again, in pain. And in this case as well, there are no excuses for such acts, absolutely no justifications, but there is the pain and there are the facts. The facts are that healthy people don't commit crimes like this. The facts are that people who come from abusive homes sometimes feel they'd rather infect other people with their pain than handle it in the right fashion. These people are not monsters, though. They are weak. They are broken and weak and ignorant and alone. And they need to be punished for their disgusting acts, no doubt. They need to be punished for infecting others, they need to be punished so that they learn to have strength and help themselves instead of giving in and hurting everyone else.
I am sick from this. I am sick with worry and despair and fear and revulsion. But I don't hate the people who do these things. I feel terrible for them. I feel so sad for them, that their lives led them to these acts of disgust.
I am so very very sorry.
