رضا: well in all respects رضا those sentences look foreign. I guess IF You had to write it out with the adverb that you chose.. I would say..
1) In what could loosely be called your life, you've made a living watching others.
and
3)In what could be loosely called your life, you've made a living watching others.
but I don't think a scholar would include the word loosely in the sentence.
In what could be called your life, you've made a living watching others.

and in your second example none of the sentences make sense..
He may have gone out. would be the correct way of expressing this..

ScarletRose: Nope, you haven't confused me at all. Well, the first sentence is a direct copy-paste from a movie named Saw II. So I wouldn't say it's wrong. Maybe not polite enough? If that's the problem with it, well that movie isn't a kind of 'polite' movie at all.
About the second example, I just figured it out that you're saying that because both may and probably have the same meaning.
