Could go either way
A simile - "Yeah, they're selfish, inconsiderate, greedy but look at yourself, you're being exactly what you hate"
An advice - "They're pitiful, greedy and such since they're human, but you're not, hence you shouldn't be like them"
And what Rood had in his mind is, "Yes they might be greedy, selfish, inconsiderate etc. But they're also kind, lovable, honorable and pitiful creature". In short, there's good and bad in them, he prefer to look at the good side.
