The parts of the statement  “He walked with wise men shall be wise” and “a companion of fools shall be destroyed” are opposites. It means that if you hangout with people that help and benefit you, will make you a good person. If you hangout with bad people who do bad decisions, you will go down in life like them. In reality, people who help each other and don’t do drugs will succeed in life. Those people that you hang out with are like your role models. If you hang out with bad people you will also decide to become bad. If you hang out with good people, they will become your role model so you will also become good. An example if you hang out with bad people would be someone that has good grades in school. That person decides to hangout with popular kids. The person decided to join them on whatever they do, like to smoke wee, and realized that since they fail classes, the student should too. So the student went down with the popular kids. If the person hanged out with good students, then it would have not ended like this.
