A few is quite the understatement. Aziraphale has performed countless temptations over a great number of years and on occasion has even found them a little fun. Just a little. Barely any sort of noticeable amount. Certainly nothing he'd laugh over with Crowley during a meet-up involving a generous amount of wine.

Definitely not.

"That doesn't matter," Aziraphale tells him primly. "It was for the overall Greater Good." Said as if that absolves him entirely. He had warmed up to Crowley's idea regarding the Arrangement because he had been, in fact, fully correct. Aziraphale just hadn't wanted to give it any acknowledgement. Not for a while, at least. They were going to happen anywhere and there was to be a balance, so why not share the workload?

"I don't even smell Evil," he adds. As an angel, an ethereal being, he only smells of Goodness.

He assumes that you'd track a demon through the smell. If you were human.
