I am not going to hire someone.
What reason do you have to not hire them?
He is a pedophile and he would be working with children.
It is normal to be concerned with the children under your care. They could get hurt if you hire a person who is attracted to them.
By maybe I shouldn't judge people; he hasn't done anything for me to be judged on.
It can sometimes be okay to trust your gut, if you don't feel it is okay for him to work with children, it is okay to go with those feelings. You need to trust yourself and continue to protect those children.
