Question

Hello Rabbi,
Amichai Ben-Yigal's father, whose son was murdered, together with other bereaved parents, have launched a campaign to promote giving them their children's sperm so they can have grandchildren. https://youtu.be/Kb7HebQgyek
From a halakhic standpoint, what is the discussion here?
But I don't understand how it's possible to take a person's sperm without permission. Morally???
More generally, is there ostensibly a moral problem with bringing a child into the world when, for example, he will have two fathers, assuming (I have no idea) that a child's psyche needs a father and a mother—so that seemingly you're bringing him into an unpleasant situation? Or maybe the world in general isn't pleasant, so this will just be one more point he'll have to deal with?
After all, nobody dares tell a person without financial means, "Don't have a child, because sometimes you won't be able to give him what he wants." (I'm not talking about starving to death.) I mean a reasonable level of economic hardship.
Something here really bothers me, and I'd like to hear your opinion on the subject.
Thank you.
Another question on a different topic:
On one of the Sabbaths my father told about a holy Hasidic rebbe whom the Nazis forced to stand in line, and there was a woman in front of him. He stepped out of the line, and the Nazis killed him.
It's true that it says, "Better to walk behind a lion than behind a woman," but I don't think that was meant literally or that this is how Jewish law was ruled.
And really the question is this: a person who, for example, did not eat non-kosher food and because of that died in the Holocaust—seemingly he is a person carried away by emotion. After all, he did something that God does not want. Since during the Holocaust there was no decree specifically against souls, and because of saving a life he was obligated to eat. Unpleasant as it is to say, didn't he sin by not eating and dying?!
When I tried to say this, even just as a possibility, everyone screamed at me that I'm a heretic and cold and detached. And in my greatness I did not keep quiet in response.
And at the third Sabbath meal, the heavens split open. And so did everyone's ears.
So my third question is: how do you control your temper and not explode at people who don't know how to conduct a discussion, aren't open to listening, and are locked into emotions that sweep them away?
Thank you very much.
