Mentally strong in the sense that doing something like suicide, he would consider as something completely beneath himself to ever do.
Going out either in the process of trying to take down his brother, or being pwned my Naruto because he once again tried to kill him, is how I believe things should end for him...but with the way that Kishimoto has been going nowadays, it's just as likely that he'll end up being totally redeemed, which would just irk me to absolutely no end >.>
Agree.
