People are going to have different opinions, and societal norms and beliefs shape that. If I walked up to you and cut off your head, I’d be arrested and called a savage killer. If I was in the army and called in an artillery strike that fit the rules of engagement and killed 500 people, I might be lauded as a hero.
Abortion is a tough issue as it touches on so many issues. When does a mother’s life outweigh the child’s? When does the child outweigh the mother? When does the mental health of the mother outweigh the life of the child? When does the ability to support the child factor apply? Should a woman be able to use abortion as “free” birth control?
Different people will answer those questions differently based on their beliefs and perspective.
