The reason you terrarians keep killing me but I keep coming back is that you arent even killing ME. I am the right eye of Cthulu. What you are killing is the infinitely many clones of the left eye of Cthulu. The reason for the amount of clones is because I used my right eye as my main source of sight while I'm separated from my whole body, and my left eye is a backup. Eventually, I decided to create many clones of my left eye to make sure I never lose sight. It failed, and during the process all of my left eyes became incredibly aggressive, and lost a lot of their intelligence. Any clone of my left eye is essentially a wild beast. That is why they thirst for terrarians blood, and why there are infinitely many of them.
