made by the Creator can disgust

Nothing is created by some conscious and living entity called by God or whatever. Things only happen. There is natural pattern to whatever happens. For example, gravitational pull of Earth makes things fall to the ground. Thus a very pious man and a very wicked man thrown from a helicopter will face the same fate and die. There is no conscious authority to help the pious and punish the wicked. There is neither mistake nor purpose in what happens. Only certain happenings suit some and they survive by a doctrine called 'Survival of the fittest'. Others who cannot adjust just vanish. There is no pre planning or mistake in what happens. This is only a matter of something suiting to some and not suiting others.

Creator has done his job being fair and above prejudice but we human beings have developed prejudices which make us think that certain things are disgusting..

What are those "Many things"? Can you quote an example that eats you?

viruses are the best example that they will eat him.

There are wonderful things and then there are not so wonderful things.

Nature is made up of both good and bad things

everything has its own positive and negative impact

Virtue and vice both are two sides of the same coin...similarly if you think God has created certain things..it has a purpose.

Nothing is made by mistake by the creator, every thing has its own reasons behind

Everything has its own advantages and disadvantages.
