I come from a low socioeconomic area and have seen women pop out kid after kid (one has 11) all to diff dropkick men and I do pity the kids for their mothers choices. Some in all honesty seem to just keep having them so the money keeps rolling in because they have no job or career prospects and I find that really sad that they think they have no option other than to breed.
The kids must find it hard too, in one case some fathers see their kids but others cbf'd or don't know can you imagine how you would feel to see your siblings seeing their dads but you don't get to see yours how heartbreaking.
Making one/two bad choices is one thing but to continually make similar choices over again is just IMO stupid and they are thinking about themselves and not the kids they already have.
I do feel pity for the kids (in some cases) but I don't think I judge after all I had to get a DNA test to prove dd's paternity. That was the kick in the butt I needed too now I'm educated, have a good job and a mortgage. Sometimes a bad choice can turn into something fantastic you just have to learn from it.
I don't think a child is a mistake but it can be a product of a bad choice my two are no diff I was young and naive, I thought I knew everything and didn't think of the impact on them I'm lucky their dad is good and his family are fantastic.
