Differences between Henry and Victor?

Henry Clerval is enlisted to accompany Victor on his journey; Victor is initially displeased at this, as he had wanted to undertake his task in perfect solitude. He is thrilled upon seeing Clerval, however, and reflects that Henry's presence will keep the creature from observing the progress of his work...As he recalls their journey, Frankenstein is struck by the great difference between Clerval and himself. Clerval was entirely alive to the natural landscape, which he loved with unparalleled ardor; Victor, by contrast, was wracked with melancholy, and felt himself to be a "miserable wretch." Victor mourns over the memory of Clerval, whom he still considers a man of peerless worth and beauty of soul.
