I read mostly science-fiction, and time travel is one of my particular favorite subgenres. In most of these, it's considered a really bad idea to attempt to change the past; one series even has a Time Police to enforce preservation of the timeline.
Time travelers is a feint, it is an alibi for the guilty. Spying on Donald Trump was done and okayed by President Obama. Occam’s razor, the simplest explanation is usually the best one.
