Because my motivations changed. Because I began to care for you, and my friends, and my city, in a far less superficial way than I did when I started. Before I even considered taking over Queen Consolidated.

During the siege, my fiance was killed by one of Slade's soldiers, and I couldn't do anything about it. And that was the motivation from the start.
And you, Oliver, everyone changed me. That is why I'm the ATOM. It's why that's never going to change.
