Did you like the new villiain from the new star wars movie ?

I think Kaylo Ren has has evolved but he has an childish attitude, I mean he gets angry very fast he can't control himself and finishes killing the one who put him angry, but we can see that he's not bad, he has internal conflicts, as I see it, his side isn't defined yet. Disney presented a new type of villain, from my point of view the scariest one I've ever saw, because you don't know what he is able to do when he has one of his childhood tantrums. What do you think abaout this new villain that present us disney ?
