Hey hey, Ares guild. If you want to charge him with murder, you don't have to stage it. He'll gladly do it. He'll kill all you higher-up little shits who want to cause trouble for him, for free. Pretty sure no human who passed the tutorial tower can kill him anyways.
Seriously, despite his strength and him constantly showing a lazy, non-caring, loner attitude, the Ares guild's top brass seem to be convinced that he'll be a hinderance to their development and insist on causing him trouble and invoking his ire.
In case you idiots haven't noticed, he doesn't care about authority. He literally showed up to an awards ceremony, meeting the high ranked politician in his usual sloppy attire and walked away immediately after it was done. So what if you charge him with a crime? What, you think he's gonna get arrested somehow? By people in the rest of Korea, no, probably the entire world, who can't even keep up with him in speed or strength? You want businesses to deny him service or something on the premise of him being a murderer? Like hell that's going to stop him from taking food from convenience store and leaving the money for it behind.
Literally, framing him for murder doesn't really hinder him in any way. If anything, it gives him an excuse. If he's going to be known as a murderer anyways, might as well kill everyone in the Ares guild that is trying to inconvenience him.
