It's not necessary to take it that far.

The lesson that certainty and how you frame your view of the world to other people has a massive impact both on your own world and those around you is valuable, and does not require a flexible attitude towards ethics even though that same lesson can of course be horribly exploited by those that does have a flexible attitude toward ethics.

Most of us distort our own reality. The problem is that a lot of us interpret it more negatively than it really is. E.g. shy or introverted people have a tendency to remember peoples reactions as more negative than they actually are, and to underestimate how well we come across to people we meet in person, and so give up on a lot of opportunities.

Consciously "tuning" your own distortion field more towards certainty and focusing on the positive can be immensely beneficial without requiring you to turn into a liar and manipulator.
