Is Voldemort capable of human emotions such as love and jealousy? When he failed to kill Harry did he suffer an irrational fear of revenge against him in his weakest moments?

Well, we know he can feel hate. I think anyone is capable, but Voldemort chooses not to feel love, that was his downfall really, I think. And jelosesy, yes I belive he was a very jelose person as well. But he forced the feelings of love from himself. And maby the more he split his soul the less he was capable of feeling any love what so ever.

I think that he feels the basest, most feral of emotions. In essence, Morty is a feral child. He grew up without a basic understanding of human emotion but unlike becoming something closer to an animal, he became sociopathic. What he feels is all of the bad aspects of feeling and none of the good. He's sociopathic and narcissistic. He's a megolomaniac and a fascist. He's not balanced. I think he is pure dark, the id. Harry would be the ego and Dumbledore would be the superego, the opposite of Voldemort (in his idealized stated). Voldemort feels hate, revenge, regret, contempt, all of the negative emotions that would otherwise destroy a person. In essence, he would be what left behind after a Dementor had it's way with a person.

We do know that he can't hate, but i have a feeling he can not love, or be loved. He was never loved as a child, i think that is why harry won him over in the end, harry can love and be loved. While voldemort can not, as for sadness im not sure. I think he can be happy or at least proud, and he can probioally be disappointed. But i don't think he feels these things like we would feel them.

He certainly isn't capable of normal emotion as we know it. The closest he would come to in our society would probably be a psychopathic killer or something along those lines. All positive emotions are gone, and I believe that is due to the breaking down of his soul process which he went through when he used the horcruxes. Basically, I don't think Tom Riddle was a very loving person to begin with, now there's just nothing left at all except the negative.

Yeah, I like your point that he is a scipath Sissa, I think that hit it right on. Also like Linda said to, I think the more he bhoke and split his soul the more hate and greed and envy made their way to the forfront of his feelings. I guess a questin that came to me right now is are sciopaths born that way or is it learned. Because I always felt the Morty was born different and yet because of enviromental factors (no loving parents, being an orphan), that really brought that pre-dispoistion.

Sociopaths are born, not made. Perhaps it may not be prevalent in a child because a child normally acts on it's Id personality but as the child grows, and you see more and more narcisitic behavior and that Id doesn't recede to the Ego, you begin to realize that this person is acting this way because they lack the capability to stop, to care. Sociopaths only care for their own well-being and their own cause. They lack the conscience that most humans have to stop them from killing at will or stealing or raping. When you lack that, you have someone like Voldemort, albeit he's a bit extreme.

Ok, I figured it to be like a genetic factor. So thats cool then. So Voldy was born a sciopath, and had enviromental factors there also. Makes me wonder how much inbreeding in his genes may have had a little something to do with it also. Well, if Voldy was a classic case of sociopathy (sp?) then I would think that even if he had the capicity for feelings like love, it would be self-serving, the feelings. Does that make sense?

I believe that Voldemort could love himself, but that was as far as his emotional range could go. To expect him to feel anything for another human other than hatred would be way more than he was capable of. In a way he reminds me of Darth Vader, yet he had the capacity to feel a loving emotion in the end, after he was released from his bonds. I guess there really isn't any comparison! Maybe Megatron from Transformers, but that's a machine. Maybe Voldie was a machine, too, he actually made himself into one.

Voldermort, if he did feel any 'normal' emotion would of felt remorse, taking back his horcuxes. Voldermort feared death, so I hardly think he would even dared, the risk was too great.

I personally believe that Voldemort was still very much in touch with his feelings and emotions. After all, they are part of the human condition, and there could be some debate on whether they are tied to the soul or not, but maybe it is simply one’s belief in said emotion that allows it to exist. The breakdown of his soul simply game him a focus that he couldn’t allow himself when complete, as a fear of death and perhaps even humiliation would be ever present. He pushed these fears away, although he couldn’t allow them to be lost completely, as evidences by his severe paranoia and need to destroy Harry. Perhaps he did feel such softer feelings, but he had a reputation and goal that was higher than these, and so he channelled them into his work, his passion about his aims clearly evident.
