Doesn't Harry's prank on Neville exhibit Fundamental Attribution Error? The reasoning behind his decision to take part in it and his rationale for why it's justified both seem predicated on personality traits of Neville, hastily-assigned by limited information. Of course Harry's allowed to get into some mischief, but he should probably try to follow his own advice when it actually could have significant consequences for others (or at least get called out on his contradictions from time to time, which maybe he does later).
Further, his consequentialist argument doesn't make any sense since the consequences of his prank should be impossible for him to predict with any accuracy.
