August let OS life... does that mean he doesn't actually like to kill?

He did shoot Mirajane through the heart, but that might have been due to Irene. Irene was already a bit pissed about being derived of a chance to slowly torture Mira to death, so I guess a quick mercykill might have been something of a compromise between what August wanted and what Irene wanted.

Still it seems odd. On one hand August is helping Zeref, who wants to kill all of mankind, but on the other hand he doesn't like to kill? Or is Zeref's intention to kill everyone the one detail that August doesn't know about?
