No, you didn't kill anyone. The weapon malfunctioned because it was unfinished, and Zikon and his team stole it, knowing it wasn't finished, and now he's mad at User. His anger for User stems from User being a "problem" candidate and being the only weapons worker left that hadn't been picked so without knowing Users traumatic history with the academy (experimenting on them and such) he blames User for everything that goes wrong thinking they are just academy failure that got dumped on him (he hasn't read usuers file) And honestly you can make up why User was experimented on like for example

the second one!
