请问这句话怎么翻译(汉-->英)

I'd rather let him go out and practice more than just leave him aside for my favor.

Though I really hope that he would stay on, I would rather let him out to explore and toughen himself.

But at the thought of a better future if he could go to see the outside world, I have to let go of him. 意思很准，太罗嗦了~~

Although I hoped very much he can stay behind, but I hoped he can exitexercises oneself.

虽然我很希望他能留下来,但我更希望他能出去锻炼自己.
Although I hope that he would stay,I even more hope that he would go out to exercise himself.

even more(更，还）
exercise oneself（锻炼自己）

I really hope that he can stay, but I expect he can go out and experience himself
