What came after was that I murdered three people, [ Dorian sarcastically continues. ]

And those people I killed? They were so young. Stupid twenty-somethings, with so much potential, who's only crime was to break into the wrong house at the wrong time. Their deaths happened because I made a foolish attempt at altruism.

[ There's a part of this dilemma that Dorian is overlooking. He didn't have to kill those people. But, at least in his mind, he totally did. What else could he have done, just accepted his own personal hell? ]
