Not officially become a monk but your heart, becomes detached from whatever is not permanent in this world. Detached from whatever is not conducive to your spiritual elevation. Then, you will also gradually or quickly become Arhat or even higher, Buddha. Apart of being compassionate and merciful, we all have to be responsible for our group, for the reputation of us so that we can go out and spread the better teaching. If you do the same like them, how can you tell them to become better?
