Your reasonably new so I understand where your coming from but -
1. All of this has been said hundreds of times before
2. People will continue to hate on him regardless of how people defend him
I'm not trying to be rude or anything it's just the honest truth here on the base. Sasuke is and will continue to be a polarising character. Some people like him for his 'cool guy' attitude and jutsu, others think his childish, boring and arrogant. It's a matter of opinion and no ones is more valid then anyone elses.
The one thing you should take out of it is that Kishi obviously can make excellent characters, since people invest emotion (positive and negative) into sasuke's character. That's pretty cool at the end of the day......
