Since we were born in sin, are all sins justified just by saying, "I was born this way?

We were all born with sinful natures. Doesn't that mean, then, that we have the choice in life on whether or not to act on those sinful natures? Pedophiles, s, gender trading, lying, adultery, deception, outside of marriage, murder, etc.? Would a pedophile be able to march in the streets, get a coolition together of other child molesters, and get legislators to make the rest of society accept their lifestyles because they were "born" that way? Since children are murdered in-utero, would children also be "fair game" because, then, the rights of pedophiles would be more important?
