Pechorin is the sort of man who will do anything to get what he wants, regardless of rules or morality. He is confident and unconcerned about getting in trouble with anyone. He has a lot of charisma, which helps him in his plans. This sort of man can be very appealing to some people. However, he kidnapped a woman and coerced her into becoming his wife. While technically she agreed near the end, I hope no one is honestly going to argue that that act was totally fine, morally. (On a side note, I'm thinking she had Stockholm Syndrome.) In short, I view him as intensely charismatic and appealing, but ultimately distasteful man.
