So putting the parasite in there should just leave you attached to it. Why should it? The consequences of their actions are still seen through having to go through the process of abortion (which is not easy on the body or painless). Even when people make bad choices they’re allowed to seek help and fix their problems. People that eat bad food can be given medicine, people that overdose are given medicine. People that choose to smoke and get cancer still do get treatment. We don’t hold on treatment from people just because they made a mistake. Now if you want the consequence for sex to be the possibility of losing your life or going through incredibly pain then it’s on you. There are consequences to getting pregnant. Also, looking at the statistics it’s the most vulnerable that need abortions. Women who are already mothers make up the majority of them. Also, people with poor access to contraception and or sex education. Sex always carries the risk of pregnancy, but we shouldn’t impose the consequences to be carrying an unwanted child against their will. There are consequences enough to last a lifetime. The moral stigma and the pain are enough.
