people that make fun of others are evil?

Not necessarily evil. More likely just insecure, with a poor self image.

Making fun of people is rude, hoping they burn in hell is evil.

Humour can be alright in the proper contest, however the Bible condemns making fun of those who are disabled.

“‘You must not curse a deaf man or put an obstacle before a blind man, and you must be in fear of your God.....Cursed is the one who causes a blind person to lose his way on the road.’    Law of Moses

i agree why hurt others when you can help them instead?

That isn't a question, its your personal opinion.

Yahoo is not a chatroom, not an opinion message board.

You are free to think what you like, but if you must post your stuff use Facebook or Twitter or some other social network.

'Sin' is imaginary (as is 'God').

Making fun of people (especially those who are powerless to stop you) is pretty low - but nobody 'burns in hell'.

The best you can hope for is that they get their comeuppance in this world.

You are quick to cast people into hell, so you should be very very careful about what you do also.

 Matthew 7:1-3

 “Do not judge, so that you will not be judged.  For in the way you judge, you will be judged; and by your standard of measure, it will be measured to you.  Why do you look at the speck that is in your brother’s eye, but do not notice the log that is in your own eye?

In regards to what God hates:

Proverbs 6

There are six things that the Lord hates,

Seven that are an abomination to Him:

Haughty eyes,

a lying tongue,

And hands that shed innocent blood,

A heart that devises wicked plans, 

Feet that run rapidly to evil,

A false witness who declares lies,

And one who spreads strife among brothers.
