If this is happening only in Bhutan but not in other Buddhist colleges or monasteries, something is wrong and the abbots should look into this seriously. I have also read elsewhere that many of the younger monks in the monastery were ordained against their will, mostly due to their family in poverty, so it is no surprise that this kind of problems crop up. It also means that the abbots are not doing their job well. Something needs to be done about this before Buddhism degenerates even more from here in Bhutan, and it is the teachers' duty to educate the monks on proper behavior.
