If this is what you think, then I have good news for you–it’s not true.

We are not under a curse because of the personal sin of Adam and Eve or anyone else. Many people think that’s the case, but it’s because they have a faulty understanding of the results of Adam and Eve’s sin.
What happened is simply that by being disobedient, Adam and Eve LOST saving grace. God had intended they should live forever (hence he supplied them with the Tree of Life), but they chose to eat of the Tree of the Knowledge of Good and Evil, which was forbidden to them. When they did that they LOST the life God had intended and they LOST three intrinsic attributes we humans cannot regain except through God’s grace:
They lost (and we as their descendant lost–you can’t pass on what you don’t have) an unsullied will, unsullied ability to understand, and the unsullied desire to do what is right–all three have been “darkened” in us, like turning off the lights. All of us have failed in these areas to greater and lesser degrees because we are wounded and in need of healing. We are “stained” with original sin not guilty of actual sin at birth, so you can’t be punished for grabbing the “apple” since you didn’t do that, but you don’t have the ability to always know if the “apple” in front of you is good or not, the unsullied will to not take it if it isn’t or the unsullied desire to resist if you want it anyway–it’s why humanity is in the mess it’s in and will be until the end of time. Adam and Eve did know the difference, had the ability to fully understand, and could have desired to do the right thing, but took it anyway–so they were deliberately disobedient. No one can accidentally or by mere birth commit sin.
Baptism removes the stain of original sin, but we are still wounded and in need of the only remedy–God’s grace. This we receive primarily, but not exclusively, through the sacraments Christ established.
