Any chance for a bit of tossing off Itachi huh.
"Shinobi don't cry. They mask their feelings." - Failed
"A Shinobi's priority is the mission" - Failed
He also failed the standards of being a human being. Slaughtering his family and obviously twisting his brother (Itachi had no idea he'd be brought back to settle it) itachi really did fail at everything he set out to do. So don't make him out to be some godly figure.
I was literally about to list a bunch of examples of supposed 'real shinobi' but honestly, what's Even the point? Just another dumb Itachi fan.
