It might be helpful to define “trust” before deciding.
Trust can be internal or external.
Do I have faith in my ability to respond successfully to lifes challenges.
or
Can I manage and manipulate my environment to my satisfaction based on my abiity to predict the actions of others?
We can learn the internal kind of trust by learing to rely on ourselves.
We will too often fail in depending on our ability to predict the actions of others because people have a habit of doing the unexpected.
So the question, “Should I trust the others” obviously puts you in the position of having to rely on the others rather than yourself.
If, in your best judgment, the others are of like mind, have integrity, agree with your proposition, and are likely to follow through, then yes.
Blind faith is a slippery slope.
