No, birth control is used for birth control - IUDs, implants, the Pill, foam, diaphrams, condoms, vascectomies, tubal litigations, et cetera.
Sometimes those methods fail.
Back on topic, quality-of-life abortions are something I support. I've seen cases where a severely deformed baby died hours after delivery. I've also seen cases where a severely deformed baby survived. In every case the family's finances were drained. The other children got very little parental attention, because the parents had to spend most of their waking hours caring for the deformed child. The severely deformed children spent several months per year in the hospital and were in constant pain. They spent most of their lives in bed.
I grew up in the thalidomide era.
