I Do Not Support the Spread of Christianity

I have grown up surrounded by christians and there is something I cant understand about the religion. God doomed Adam and Eve to mortal life, he also doomed each and every human born after for the sake of their mistake to eat from the forbidden tree. Now everyone is born a sinner and needs to be pured by being baptised. And god is so judgemental and unforgiving that he will judge you one day to heaven or hell. Is this a religion of love? Love is unconditional, how come this religion is not?
