OP did the right thing, it's sometimes easy to fall into second-guessing yourself like this but you shouldn't. It's a universal constant that people wish the world was a better place... well, what you did was help make it one.

I would have done whatever I was qualified to do for as long as I was capable. I'm kinda biased on this though since it's not just a strong recommendation for me but an
order straight from the top.
