i guys i wondering if we end up in a situation of disadvantage, can the enemy be tricked or they can hear our thought and fool us instead?

It really depends on how smart the person is. A person that is really smart that knows the truth could use their own narrative against them for whatever and sense and counter any manipulation. Maybe trick them.

Someone who really doesn't know what they are doing is probably going to end up getting tricked themselves. They are really smart too.
