Do you believe life is created equal?
This is a loaded question.
All life is deserving of consideration and respect for its role in things.
That said, no - life is not created equal. My cat, as much as I love and adore her, is not my equal.
The reason we've created this whole mythology surrounding "equality" is because lesser beings have difficulty appreciating the reasons of our inequality while failing to respect the natural laws of the universe that, eventually, render us to the worms.
Is abortion right or wrong?
That one is circumstantial.
I think it is more wrong to try and delve into the wombs of others. While it is obviously a less than ideal solution - you will note that the people so adamantly opposed to this procedure are not lining up outside of orphanages and signing up to be foster parents.
People get too emotional over it.
It can be reduced to a question of functionality. If people simply go about killing each other because they've angered one another - then that's not going to lead to a very functional society.
By that same token, a society that completely rejects the notion of killing people who are nothing but problems will, also, become dysfunctional. As will those that reject the notion of self defense.
Is the world meant to be unfair?
Humans are meant to come up with ideals and work towards establishing those ideals as the standard.
Though the world is not set up for those ideals to function based on the merit of their intent. Hence why there are no utopias.
The reason our attempts to realize these ideals fail is due to the fact that our ideals are exclusive of the real world demands placed upon any system that attempts to function within it.
It's like trying to build a house without consideration for the fact that the wind will blow and the rain will fall, or ignoring the fact that you do not have a stone strong enough to create the vaulted arch design you wish to use. No matter how beautiful and decent your intentions are - they simply won't work if you forget that there are things outside of: "This is an amazing idea!"
