I treat them as I see fit. They suit my purposes well and there are no complaints. They're a tool, like I was.

[ Servants are tools, familiars for mages to use, nothing more and nothing less. To Berserker, his shinki serves the same purpose -- a tool.

The only similarities between the two are the fact that this cold killing machine is a part of him. Remove the empathy, remove any joy and warmth, and this is what remains. He is too corrupted by the Grail, by the circumstances of his summoning to have that warmth. A possibility that could not be, that shouldn't be. ]

Hmph, don't concern yourself with how I achieve my goals. Don't stand in my way and there won't be a problem.
