Eh, I dunno...
Kubrick wasn't too pissed off, and instead reacted quite politely, when he found out that his buddy Gordon Walker (A vampire hunter that was, I'd say, about 167% as driven as your character) had been turned into a vampire himself.
He did, however, (politely) insist on Gordon to kill himself, or to let himself be killed by Kubrick. But, that's just a tiny detail. Probably as tiny as Gordon killing him in anger, because he wanted to kill the vampire who turned him into one, for revenge.
But, given that happened in the 1960-1980's, instead of in the 150BC-200AC, I'd say that your friends may be a little more short tempered about it...
And, yeah, ofcourse ring mining, piratehunting and mining site security would be excellent ways to make cash for my E:D character, however, mining racks in at about 6-7 million dollars/hour, whilst pirate hunting and security probably do in some lower, because they're a lot less reliable ways of earning cash, and not to mention, risky.
Ofcourse, 6 million per hour doesn't sound bad...
But, if you reccon that my federal corvette has cost me about 600 million dollars, just for a basic A-rated NPC fighter build, and I'm also going to want a 'conda, wich would cost me another 400-500 million, and I kinda need a python too, because both the conda and the corv can't land on outposts, and a python should cost me about 200 million, if I'm lucky...
Well, I guess you can see why, in-game, I'd rather get into the much more profitable slave-trade, as they're both equally brain-dead grinding exercises, but at least the latter will get me there in a reasonable amount of effort...
