I recently took out a ball valve in my shower area and replaced it with 1/2" copper pipe using 2 couplings. After I was done soldering the couplings I noticed the pipe was bent slightly in the fitting. I turned the water back on and there were no leaks. Will this cause the joint to fail over time?

pipe
It depends and there is no way for us, or you, to tell. A copper solder joint depends on a very tight fit between the tubing and the fitting. IF the cocked pipe caused a larger gap inside the fitting, then the sweat joint will be compromised at that point. But whether that would cause a leak or joint failure sometime in the future depends on how badly it was compromised. I have seen terrible solder joints which held for decades, and then fell apart when something touched them just right.

It is impossible to determine is a sweat joint is okay unless I make it myself.
The repair coupling may be off center on the joint or it may be fine.
I have no way of telling.

If possible, pump up the system to a good test pressure(according to code) and test it with air before closing up the wall.
Is there another shut off that is more accessible so you can shut the water off later if needed?

test
60 # of air, or system water pressure will both reveal a leak. There is nothing intrinsically better about air.
