My reasoning is that Mr. Itoh put an intern in charge of a system that could cause major damage. It's like giving the intern keys to your AWS console and shitting your pants when he terminates all you EBS root disks that you didn't back up.

Mr. Beck wasn't culpable because he didn't understand the full effects of his actions or the tension of the current situation. Ioth should not have let Beck in the door that morning and he should not have given that much power to the intern.
