No, it'll backfire spectacularly, and I've lived it. When someone's a habitual liar, people will get accustomed to them and nobody bats an eye. But if you're always honest and one day you fuck up and they find out, word will spread, the rumor will grow, and it'll create a bigger ripple. You'd have broken a realiance where people will feel the need to adjust their views on you.

This isn't really unethical tho

Until it’s discovered and pinned on the regular fuckups that you’re just that much more methodical and that makes you much worse if not the main dangerous sociopath of the friend group.
