Similarities
Heaven and Hell both begin with the letter "H".
People go to either Heaven or Hell when they die,or so it is said.
Both are not on Earth.
Both are TOTAL OPPOSITES!
There is something to do on either one,I think.
Both have main colors.
They both have leaders,I think.
Pets have whole different ones,or so it is said.
THE MAIN REASON IS:
No one actually wants to die,so in reality,both dimensions aren't DESIRABLE.It's just that one dimension is more desirable than the other one.
