Bent a chain link back into alignment. Will it hold?
Your chain is very likely weakened because the joints between the outer plates and pins will have been deformed. Yes it will fail when you are applying maximum torque, likely when you are goin uphill. The problem isn't so much being stranded, it's the nasty crash you'll have when that happens.

You can't just remove an inner and outer link because the chain will then be too short. If you previously replaced the chain and have a few spare links after you cut it down you could splice in a few links.

Personally, I'd just replace the chain.
