I was thinking of something pretty cool and it goes like this...

You enter a cave and a trainer runs towards you asking you to catch its pokemon because it broke loose of its ball and his parents gave it to him and it has been in his family for a while...
You can either decide to be good or evil and catch it and keep it or catch it and give it back... if you give it back the reward will not be as good... but you will be able to feel like you did the right thing... the pokemon would be a steelix.. at level 47 (yes i know im specific haha)... the reward if given back would be a rare candy...

good idea? bad idea? suggestions?
let me know
