Why did Jesus suffer for sinners and not victims

[John 6IX Breezy]

Your argument seemed be that if we don't accept abortion, it will/might lead to forced kidney donations.

No we're saying if you can justify using someone else's body for one purpose why not another. 

Unless you can show that the consequences of denying abortion makes forced organ donations likely to occur, the argument is invalid. The fact that abortions have already been outlawed for much of history, and no such event ever occurred, demonstrates that this is a slippery slope fallacy.
