Sasuke's character is marred by indecision, dissimulation, mendacity, and false virtue. He is painted as nothing but a back up to Itachi with no moral pretenses to stand on. He has no logical self-growth and is completely reliant on others around him to shape not only the path he chooses, but the very person he is. He has the mental capacity of a child with tantrums to match and no actual definition or relevance besides what Kishimoto has shoehorned him into on the coattails of others.
It is unsurprising the Sasuke defenders are mental midgets. These characters are a literal dime a dozen. He's a poor man's Lelouch, only inconsistent, shallow, and not well done. Hate the truth all you want, but it doesn't change the facts presented, even in your doltish ways.
