It's the will of the people who bothered to show up to express their will, which is basically the bare minimum of "will". They didn't say the preference of the people
Heck no, you don't get to dodge your responsibility like that. There's an electoral system in place, you deal with it as it is, you don't show up it doesn't mean you disagree with both candidates it means you agree with whatever candidate everyone else chooses for you. A vast majority of Americans agree with Trump as president, that's the state of things.
Not voting just meant that they were fine with whatever the majority wanted. Like the trolly problem even not choosing is actually still a choice and those eligible nonvoters are culpable.
Ah but you're forgetting that if everyone who didn't vote did vote, and happened to perfectly agree with me politically, my favorite candidate would win!
