Well in game problems like people being killed in a seemingly random manner should be addressed with the proper in game RP. I have yet to see you involved directly with any RP of mine, so until you witness our RP at the mine or somewhere else I suggest you not make such remarks.
Like I said, Ikon just learned of Kiso's recent actions in game through someone and he has a punishment organized on his return. Dealing with in game differences in a manner that will get the message a crossed to him about our guilds stance on senseless killings while also making a RP event out of it. Maybe you can take your differences with Irec in a similar direction?
I ask you what group of sentient creatures is without faults? Unless completely "brainwashed" people will act on their own from time to time. In game I see it simply as acts that should be punished when they are unearthed. These little "issues" are what makes up human-human interaction, and should make the best of them.
Cheers
