Yes, it's very hard for you to understand I know. You can think it evil all you want but fortunately women who do have children and who choose not to know the reasons why for themselves and don't require your approval.
Actually, I think YOU don't understand ME. And understanding is the key. If you UNDERSTAND something, you can make a judgement about it. If you don't, then all of your ideas about it will go wrong.
I make NO personal judgements about YOU personally. I don't know you. I speak only about the ideas, and the IDEAS are bad - though very often the people who hold them are kind, loving, full of good intentions, like my best friend from childhood leading the fight for "LGBT" "rights". He was my best friend for many years and I know a ton about him. But his ideas are terrible and will tear apart our society. I love him and can say dozens of good things about him, but his world view, the nature of truth, sex and human relations, is wrong.
As to "thinking it evil", we'd need some clarification. I think it entirely Orthodox to be "husband-free" or "wife-free", especially if you are a monastic. But the determined philosophical avoidance of children - either because a married couple is trying to avoid children or because a single person is avoiding marriage NOT because God has called them to a monastic life but BECAUSE they want to avoid children - is wrong. It is the wrong attitude towards life, towards the family, and towards children. It is a massive form of ingratitude, for we were all children and all want to enjoy the good things in life, yet are focused on the self to the point of denying it to children, refusing to "pay it forward".
Again, I make no judgements about you, and I can certainly imagine temporary situations (the sort a priest would bless) that can require abstaining from marital relations and consequently children. But the term "child free" represents a determined philosophical stance outside of any monastic, or even Christian context to not have children - ever, and to see that as a good thing.
There is a fairly simple test - that of the married Orthodox woman flouting such a stance that has suddenly found herself pregnant. She has set herself against having children, and has taken all of the modern means to prevent them, yet God has given her this child. What now? What good are all of her "child free" slogans and assertions? We know abortion is murder. A huge part of Orthodox Christian life is смирение, humbling ourselves to whatever God gives us. But the "child free" slogan says "I will not have it!" this is nothing other than the same pride of self-will that brought about the Fall, and that we all experience, and are called to crush, on a daily basis. The nature of the "choice" is that it says "Let MY will be done, not Thine!"
