Hell is very real.  No one chose to exist, yet through no fault of their own, by no fault of any of the decisions people who suffer with chronic illness have made, people with chronic illness suffer every day with no hope of relief.  They suffer with no hope of relief.  That shows the existence of Hell.  Christ came to show He is the Living God by actively healing people with chronic illness, directly showing his power over Hell.  None of your gods healed people from chronic illness.  It is just like your religion to claim any god is an avatar of vishnu.  That is not impressive.  You have decisions to make which can lead to escape from Hell.  But people suffer from no fault of their own decisions and you think you can escape suffering after death while you had the knowledge and ability to make decisions that could save you?  I believe in Hell much, much more than the existence of Heaven.  An afterlife of existing as a spirit is undesirable to me.  Existing as a spirit means you know you are dead.  It is an uncomfortable feeling.
