There's a huge amount of compassion in this thread which is good to see, but there is also nonsense and downright misinformation, but that's OCUK at times I guess... It is not illegal for a vet to release a 'pest' for a start. But anyway...
It's a young magpie, and in the corvid world, magpies are the lowest of the low according to other corvids. I'm not surprised that a crow was attacking it, magpies are competition and a danger to their own young.
Anyway Ejizz, you appear to have done the right thing, and at the end of the day it's a wild animal and deserves to be living as such. It's up to it now to make a go of it, seems harsh, but that's nature.
In the future though, it's probably best to leave things like this to take there course, as hard and unpleasant as that is. It was probably waiting for a parent to come back and feed it, and is one of the natural hazards of being a fledgling and also the reason that birds have so many young. Many don't make it, if you think about it, we wouldn't be able to move for birds if they all survived.
Kudos to you for trying to help though, I'm sure it appreciates it!
