Its hard to say but its possible. 'cause thats what sasuke was mainly known for. He was the curse of hatred personified xd However recently, he found out the truth about his brother and joined him in battle. He's certainly developed 'brotherly love' again but his brother has the opposite ideal. He doesn't believe in the 'curse of hatred'. Itachi may have died as a bad person but once he was revived, he was in a way given another chance to do good. He took the opportunity and succeeded.
