The kind of effort and forethought that went into this assault clearly demonstrates extreme sociopathic behaviors and tendencies. He definitely should go to prison for more than 2 years, considering his response to this extremely common occurrence (being beaten at an online shooter by another player). I mean, SIX MONTHS over a stupid CS match.
I find it strange how lenient his sentencing was. He's really, really lucky his victim survived (despite the misleading title, it looks like the victim did make it, right?)
