Where did you see Sasuke being lazy?
When he was in the coma in a hospital's bed?
This is exactly the annoying thing in the Sasuke's haters (and ponctually on some other characters too) they try to built some poor excuses to explain their hate.
If you say : I hate Sasuke, I dunno really why but I hate him, or because you don't like the stereotype of the dark avenger or whatever, well okey, fine, you can't like all the characters.
But stop inventing thing.
lol seriously I hate Sasuke because he's lazy
Get real 3 secondes please.
Sasuke is about the same level of Neji without using his seal, the only genins better than him are Gaara and Naruto, not because they work harder, but because they have a demon inside them.
Lee was the only ninja who could only counpt on his hardwork.
And he lost.
Hardwork<Genious<Demon.
Maybe sad, but true.
Each time the manga has shown Sasuke training, he was serious, both Naruto and him trained all the nights for the tree thing and
So Sasuke lazy? lol try something else.
And for the Oro/Jiraiya point.
