To be fair to them, it is hard to acknowledge you've fucked up and learn from your mistake if people mock you relentlessly about it. The easiest human reaction is to deny or retreat, not admit failure, ask for forgiveness and move on. That's why extending an olive branch and offering a safe space to discuss the issues they might be facing is the right approach (yeah, I know, it's ironic that we are even having this conversation about people who are quick to malign anyone who asks for a safe-space... but whatever.)
