This is often a subject that conjures a certain amount of emotion.
Technically speaking, any abortion carried out is killing.
Coming back to the subject, all the comments that I have read expressed by friends who are practicing Buddhist who understand dharma, karma and compassion. Maybe we should move one step back and understand the lady who, unfortunately, found herself in this terrible predicament. A raped victim having suffered such trauma would most likely curse and swear for the traumatic experience and would not be very receptive to any talk on karma or keeping the child to allow karma to take its course.
Therefore, in her mind there is only one choice and that is to abort to save her all the painful memories and resentment she had just gone through and least of all to keep a child as a future reminder of the agony. Talking to her requires a lot of skill and patience. There should not be too much preaching on what is right or wrong. In the victim’s present mind, would not comprehend what is right or what is wrong but only resentment. Sometimes compassion also means to look into another’s point of view and to feel their suffering.
In conclusion, abortion is killing and shouldn’t be done for whatever reason. True compassion is when we are able to skillfully convince the victim to change her mind and see the light. On another note, to bring up the child with spiritual upbringing or offer up the child for adoption.
