In Canto II, Childe Harold expresses his preference to wander alone, away from the general throng of humankind. The importance of the individual separating from the mass of humanity is a typically Romantic posture. Harold seeks out the solitude of nature and in these passages contrasts it to crowds, which he calls the "the shock of men." He says he would rather be a lonely "eremite," or hermit, on an island than in the midst of people.
Childe Harold is typically Romantic in seeking out and responding to nature. He feels more alive and himself on a lonely island, amid "waves so blue," than around people. Here he can be himself. He finds nature holy, or "hallowed."
The quintessential Byronic hero, Childe Harold carries with him a sense of injury and pain. He does not find himself through community or human interaction but by relentlessly seeking his own path. He "hate[s] a world he had almost forgot."
