Abortion is Absolutely Justified
Premises:
Moral worth is based on current capacity for sentience, as only sentient beings can experience harm.
A pre-sentient fetus lacks the ability to experience harm and has no present interests.
Forcing a sentient person to remain pregnant imposes significant physical, psychological, and emotional harm.
Future potential does not create present moral worth; moral status depends on actual characteristics, not hypothetical ones.
When a moral conflict arises, the entity capable of experiencing harm (the pregnant person) has greater moral weight than a non-sentient fetus.
Conclusion:
Before fetal sentience, abortion is morally justified because there is no meaningful harm to the fetus, while forcing pregnancy significantly harms a sentient person.
