No matter how frustrated you are with the speed of your computer, hitting the keyboard or rapidly clicking the mouse won't make it work faster. Also, the screen doesn't have ears so yelling at it won't make the information load up faster. Your equipment will last longer and respond better if it's cleaned regularly.
This is why I typed the above material.
In Halo Anniversary, one of the terminals you find explains how the Halo rings are used as weapons. 343 Guilty spark, the A.I. narrarating the video, just talks about killing all life in a Galaxy. All of that death, just to starve the flood. The machine didn't sound like it cared about mass extinction. Probably because it doesn't feel pain.
