Yeah, Kakashi never meant to kill Rin. He may have killed other comrades though, because if I recall as he was yelling at Kinoe (Yamato), he accepted being called Friend-Killer Kakashi, but he never meant to kill Rin. So maybe he killed others, but Rin was the one he never meant to kill.

And @Thekillman, at least Kakashi brought himself up to do it and fought him with intent to kill. Hiruzen didn't even as he saw the horrors Orochimaru was working on, and let him go.
