Doesn’t matter if they willingly joined Hamas or not.
And I’ll answer it again since your comprehension skills are that of a four year old. There are people too stupid and/or too lazy to use protection while having sex and then end up with an unintended pregnancy. They know full well that they can just get an abortion which therefore means they used it as contraception. Again almost half of all abortions are “repeat” abortions so before you tell me that it doesn’t happen why don’t you prove that it hasn’t. You won’t because you can’t.
