I agree that the important part of this as being about "untreated". I think it's a valid question to ask.
Vepin, it sounds like you were aware of your issues and worked to be a good parent, even more than other parents, because of your history. I wouldn't call that "untreated". I found it hard to read what you wrote at the beginning. It's hard for me to read that someone had children in order to try to fix severe problems in their life, and knew that was why they were doing it. Sounds like you also knew what the problems were and that you needed to fix them, I think that's the difference.
First off if they are mentally ill, they may not be in control of themselves... Second, mentally ill does not mean second class citizen. If they wish to have a family, that is their right.
People have the right to have children, but they don't have the right to abuse or neglect them. People don't have a right to take inadequate care of their children. It's a high risk that this will happen if you have serious mental health issues and are not getting treatment. Children have rights too.
I think the question isn't whether people have a right to have children, it's whether they're being irresponsible in having them. Rights come with responsibilities. My rights don't exist in a bubble where I only have to think about me. I'm expected to exercise them responsibly.
In my country I have the right to buy fireworks and set them off at a party in my garden. Say I'm not in control of myself or I know I don't understand how to handle fireworks properly, but I want to buy them and set them off at my party anyway
without any safeguards or help, because I have a miserable enough life and I have the right to some enjoyment like everyone else. I might have the legal right but is it responsible to my guests and neighbours to do that? Is it fair to risk injuring them for life?
It seems to me people with
untreated mental illness who have children do so because of three reasons:
Not knowing. Someone might not realise the extent of their issues and their vulnerability, for a number of reasons. In the case of having children, they might have no way of knowing that their parenting would be so affected.
Willful blindness. For example, a lot of alcoholics refuse to admit to themselves how serious their problem is, but they do know and are choosing not to face it.
Idealism. People can believe that their love for their children and their good intentions are all that's needed. This is unrealistic, but when we've been damaged ourselves we can have very poor judgment and awareness.
I think being taken advantage of still comes under one of those three. Having children in an abusive/manipulative relationship, for example - in my opinion the reason for being in the relationship is related to the above three things.
I think it's very difficult to say if people are/were capable of making other choices. It's very hard to say what's not knowing, what's idealism and what's willful blindness.
I've suffered all my life because my parents didn't address their own mental health issues. So I very much understand anger about this. It's too difficult for me to say my parents couldn't help it because they were traumatised themselves. Maybe they could help it, or some of it. Maybe not. I don't know.
