Frankenstein's Monster a bit like Perry Smith

I have just been watching Capote, which reminded me of his book In Cold Blood, which I read last year. One of the murderers from In Cold Blood reminded me of Frankenstein's monster. Perry Smith was an artistic sort, who yearned to be educated, yet he was filled with rage, was self-pitying, and capable of committing terrible acts of violence. He was only about 5'4", while Frankenstein's monster was at least 7', but that hardly matters. What matters is your willingness, or lack of inhibition in doing these dreadful things. When Frankenstein's monster complains about the neglect and abuse he suffered, to me that sounded like self-exculpation for the wilful acts of murder he committed on victims who had never done him any harm.

I think Perry Smith is crazy. While Frankenstein's monster is a victim of circumstance.
