Do You Believe In Hell?

Every Sunday, after Mass.
I would see a young boy waiting in the back of the church.
And then, one day, the boy confessed to me that he had beaten his dog to death with a shovel.
He said that the dog had bitten his baby sister on the cheek, and he needed to protect her.
And he wanted to know whether he would go to hell for this.
I told him that God would understand, that he would be forgiven, as long as he was sorry.
But the boy did not care about forgiveness.
He was only afraid that if he did go to hell, that dog would be there waiting for him.
