Tired of being on the heights I deliberately went to the depths in the search for new sensations. What the paradox was to me in the sphere of thought, perversity became to me in the sphere of passion. Desire, at the end, was a malady, or a madness, or both. I grew careless of the lives of others. I took pleasure where it pleased me and passed on. I forgot that every little action of the common day makes or unmakes character, and that therefore what one has done in the secret chamber one has some day to cry aloud on the housetops.

— Oscar Wilde, De Profundis
