Not hard for him, his character is almost insane the way he is played.
He attacked innocent guy who walked after the milk and only other PC's barely dragged him to car not counting other stupid things. So he will go over edge once...
Shitty storyline? There is hard to have a storyline - this team is a bunch of morons, specially selected who fall into all traps and do stupid things. So yes, they have storyline but usually blow it

Also they die like a flies so it is hard to make a character-centered campaign. Almost every session is worth to get into CLUE files, to boot. They reinforce my faith in humanity and are so easily to manipulate.
As for munchkiny part - I have no initiation in my game, because as I pointed out earlier, I just received MITS. I *do* think that initiation gives "something for nothing", but I have no problem with players doing so. If they will start being annoying I'll let them know, in game and out of game.
Much thank you for offering to initiate in Universal Brotherhood.
I'll give him a chance to do so, certainly. Along with Blood magic.
If he will refuse and be cautious, I'll offer normal group for initiation and maybe even will lift some of his insanity. But doubtfully, he is never cautious and it is mortal sin in Shadowrun.
Yes thanks, you brought me a couple of ideas what to do next when they botch this run (going on run without ANY investigation and preparation).
