This is a surprisingly common stumbling block for devs.

@NuttySwiss @UkiahSmith “Recently, I was asked if I was going to fire an employee who made a mistake that cost the company $600k. No, I replied, I just spent $600k training him. Why would I want somebody to hire his experience?”-Thomas J. Watson (IBM)

Thanks for going further by focusing on character.
