Who to tell?

What characteristics make up a monster? We often connect the word monster with an epic creature who has super powers,unreasonable behaviors, and unrealistic body features. This question came to mind as I read the description of Killroy, the monster who had killed Elizabeth along with fourteen other women. Killyroy confessed of killing fifteen women all who were dumped on the side of the road. This monster had no heart, he had taken fifteen lives away, ruined fifteen families, and he could still live with himself without guilt.
 All had been branded with the letter K. Branded in the same way as a cattle. Killroy had took a metal poker, stuck it in a blazing fire, waited until the poker turned molten red with heat and then he seared each of women's skin with a sizzling hiss. Killroy had put these women through such pain he had made every sunset and sunrise left miserable for these women. After reading of this harsh treatment I could only imagine the pain, hear the screams of these women, and feel the their cold tears drop down the sides of my face. Turning the page, I began to predict the punishments that would lead up to Killyroy's death.
After committing many crimes Killroy was still given the right to be alive and breathe. As his victims rotted, Killroy in jail was given the right to breathe, to experience life, and to smile while making others suffer. Was Killroy not a monster? After reading this chapter from Tell No One I learned that a monster can be human and doesn't always have to have unrealistic traits. Anyone who has bad intentions and evil to any extent can be classified as a monster. In the end a monster has no one to tell; the author, Coben, says "Tell No One" but I say "who to tell?"
