Good intentions -- how much do they mean to you?

[GrandizerII]

Hey hear me out guys, I just had an interesting thought:

Let's start with the premise that all that matters is behavior and intentions don't really matter at all. It's just about good behavior, good behavior, good behavior, and good consequences, good consequences, good consequences.

Doesn't that mean that if a person denies their true self and who they are and loses all integrity... it doesn't matter in the slightest provided that overall it improves their behavior and the consequences

TL;DR: If and only if intentions don't matter and all that matters is good behavior doesn't that imply that pretending to be someone we are not is preferable if it leads to better behavior overall?

I would say "yes". The outcome is better, right? And we have to keep in mind some people just aren't typically trustworthy by nature, so if somehow they can consistently be committing overall good behavior regardless, then I wouldn't really see a problem with that. But that's the thing IRL, ain't gonna happen.
