Honestly, I do like Dmitry, but I think that he lives his life a little foolishly. I mean.... I am actually pretty far in the book, and I can tell you that there are some things that he does that are just truly reprehensible. I mean he is a pretty nice guy don't get me wrong, but I just think that he could have made some better choices.
I like Alyosha because, even though he does not condemn others, he understands that all people are not like his father. Even those who are do not require his judgment for they are under the judgment of a much higher power--God.
