What do you think of this response?

So far two children have died from not being vaccinated against measle have parents who say they don’t regret it.

I’m think if I was in their shoes I would regret it. How could you not? I mean, what if I believed my kid became autistic? I would still rather have a live kid than a dead one. I’m not saying the MMR shot causes autism. (My personal belief is that it may be that certain things like autism, just won’t display until after a certain age. Like schizophrenia and bipolar disorder or type 1 diabetes.)

I’m just pointing out that there would certainly be regret. I would hate myself forever thinking I could’ve prevented their death.
