How does the Monster's tale make you feel about him?

The monster's version of the story makes me think two things:

1) He has a point. Cruelty and the strictest isolation have led to his being monstrous.
2) He is very persuasive - more persuasive than I'm comfortable with. It makes me distrust him.

The monster is very pitiable. He is made of human parts, so it stands to reason that he would have human needs and wants. Even the loneliest person finds some kind of consolation or company; the kind of isolation the monster is subjected to, though, is complete. Worse, he has these needs and wants that are part of his nature, and he is never taught what to do with them - he is just left to figure it out on his own. For all his threats to be a scourge on humanity, out of hate and loneliness and pain, I don't think he would ever have gone through with it - he just wanted Victor Frankenstein's attention. When he extracts his revenge on Victor, and when Victor dies, the monster does not continue torturing innocents - he walks willingly towards his own death.

At the same time, he is incredibly good at rhetoric. There is a "Woe is me"-tone to his argument that reminds me a great deal of Victor. The monster sees his worst qualities as indicating that Fate wants him to be a monster, not just look like one. Especially when he talks about how his hate built up, slowly choking out his better feelings, he does it in a way that excuses himself. He is a monster, and his 'parent' neglected him in the most awful way, but he had opportunities to do something. He had a tendency to rush things and ruin them, though. He rushed Victor's decline in health by killing the people he loved, initially out of impulse, and later he sprung on old Delacey when he should have left a written note for the entire family as a way of slowly introducing himself into their circle.

I do feel sorry for the monster, and I think he was treated very harshly. At the same time, it takes a great deal of will power and energy to invest in the kind of long-term grudge the monster built up - it's an active, conscious, slow-burning fire that needs to be fed constantly. Instead of doing what he could for his own character and life, he lashed out. Maybe this was due to immaturity or a lack of experience - he had only been alive a few years by the end of the novel, and the maturity rate for a lab-originated monster is unknown. By the end of the novel, though, I trusted him as much as I trusted Victor - not a lot.
