I'm so sorry this happened to you. You mentioned that the naivite of a child helped you not remembering this as so bad. I would like to suggest as kindly as possible you attend therapy for a while to process this out of sheer self love.
You didn't deserve this and you sure as hell don't deserve the invisible wounds that this presumably left. You deserve life and love and please love yourself and your chocolate skin. :)
First: don't listen to me, I'm an idiot.
This looks to me like burned leaves due to moving them into UV light without some pre exposure from indoors. New leaves shouldn't have that problem, but the growth seems to be stunted. Also Afaik the plant will start building new roots after transplanting, which will appear like stunted growth. Give it two weeks, the just might bouncec back. I transplant beans just fine but you should keep them outdoors from the start if possible.
