Fact of life...
Only a complete idiot would think that this cannot happen with ANYONE of us. No matter how profissional, experienced and trained we are.
We are all subject to this.
There's even more senior captains, with brilliant 30 plus years careers, that screw up everything one day. It simply HAPPENS.
No matter what we say.
We can always minimize the possibilities, by new technologies, rules etc.
No fingers pointing at this poor guy. Could be any of us.
