Kills, without any OOC remarks to them in the comments Are IC, but they're the pointy end of the scenario stick. Some of them might have reasonable stories behind them, some of them might not.
All you have behind them is the assumption and your own will to build about them to make it work. In the RPsense I mean.
What I'm saying is, Leo atm has some 1400 capsuleer kills more or less according to battleclinic; this doesn't instantaneously make him a murderer. Archangels hunt for profit, Dominations hunt for sport, and if approached about it he'll just say they were tresspassing into his domain and thus were shut down; another reason why MIO doesn't deal into Leo's combat history and DED just nods and lowers his security status whatever he has to say.
'Really gentlemen, is this really necessary?' Is the usual retort though.
Leo shot down Uraniae once, but he never put any angel, criminal or similar undertone to it. He later briefy explained her she was poaching in his hunting grounds without permission, for this occassion. I'm glad she had enough professionalism to disregard that and played along without going 'OMG STILLWATER ARE ANGEL PIRATHZ' So I have to give Uraniae a +1 for keeping that professionalism intact.
Again, sorry about your ship Ura, we're kinda good at what we do and we do ain't nice :3
My point is, even though killboards aren't ICly as fuck, Stillwater's OOC and IC is as interwined as possible and kills are a part of those. If there's a specific kill one wishes to extract, Leo will probably not shrug it away, but offer some sort of a half assed explanation behind it. Whether you want to believe it or not, is up to your character. However, the idea of battleclinic or eve-kill.net being IC... like, the whole of it...
That's just absurd.
