Okay, this is vaguely unsettling, especially with the results on healthy people being good old [DATA EXPUNGED]. But still, Keter? Really, now. Keep it in a drawer, and it's Safe. It may be sentient, and might desire to be useful for that, but it's not like it can leave its case and come and get you.
Just don't have it within a hundred miles of the Broken God, and think carefully before showing it to SCP-914. 343 only knows what the Very Fine setting would do to it.
