I had the same question. Thanks!
I don't want to derail the thread with my own personal feelings and I am not asking you to agree with me. Like I said, I understand that anger is a part of the grieving process.
To answer your question (and JJenny's), there are some parents I do feel were disturbed at the time of their crime. Although disgusted by her actions, I have pity for Andrea Yates - she was clearly not (and still not) of sane mind. D'andre Lane, on the other hand, is a poor excuse for a human being who acted on anger, ignorance and lack of self-control.
If it comes to light that this shooter had motives that were fueled by anger, revenge, politics or anything other than paranoid delusions, I will be right there with you in hoping he rots. But, as of now, his behavior, his parents' resigned reaction, his above-average intelligence, his surrendering to police uneventfully, and his grandiose actions speak to me of a man made evil by mental illness.
To be clear, I am not speaking of legal insanity. That is a completely separate subject that I am not nearly qualified enough to ponder. I am speaking in layman's terms.
The comments that sparked my original post were on a news site and my own FB wall - comments about ripping his arms off or other forms of torture in a public forum. I just don't see how hate in that form serves any purpose and is in fact destructive.
