I trust only G-d. Every one of us has free will and is capable of committing terrible sins, G-d forbid.
But we must have a certain level of trust in order to function. There are many people that I love and care about. Even they are capable of falling into the trap of sin, just as I am. Therefore, we must strengthen each other morally and spiritually. We have to work together and love each other to make this a better world. If that leads to disappointments and betrayals sometimes, then so be it. We must always strive to do the right thing even if others fail us and fail themselves.
Of course, we should not be fools. We have to use wisdom and discretion. There are bad people out there, and then there are people who are not bad, just weak. We should be cautious and use common sense. But we must have a certain level of trust to succeed.
And we must always be motivated by our love for our family, our friends, and the good and righteous people everywhere. We must be motivated by our desire for justice and truth. We must be motivated by our desire to serve G-d as He would want us to.
