can it be done?

Need some advice. I live in Peru and own a 4.5m long Anaconda (he hangs out in a pool in my back garden) that weighs around 43 kilos. I've had him for 2 years but I'm not really sure how old it is.

The thing is, he's getting too large to handle and I'm worried about him getting aggressive. Anyway, I'd like to release it back into the wild. My main fear is that he's been around humans too long and wouldn't adapt. Should I go for it or donate him to a zoo?
