If you are Christian, I don't know how you cannot believe in hell as it is mentioned in the Bible several times.
Plus, where do you think souls "go" when they choose away from Christ? Christ doesn't force Himself on people - He gave us the free will not to choose Him. He does not force anyone into Heaven.
If Heaven is complete good, then the privation of good is hell. If a soul chooses mortal sin and chooses away from the good, then they have chosen the privation of their souls and have chosen hell.
The enemy wants us to believe there is no hell. Jesus died to save us from our sins, but the biggest misconception that people believe is that suddenly, the consequence for sin was completely erased. There is always a consequence of sin. Jesus' death opened up the floodgates of His Mercy and allowed us, even after sin, to fly to and be embraced by His mercy. His mercy allows us to enter Heaven. We, of ourselves, cannot. However, we cannot enter Heaven unless we first trust in God's mercy. If someone still chooses away from His grace of the Cross, then they choose eternal death.
