Translation of psychopathic in German

After breakfast we visited one of the largest markets in the country. It was very close to the hotel and we were tempted to buy souvernirs and other stuff that we would never use ever again.
There were too many of these children and they were determined to sell us a can of Coca Cola. All means were legitimate, even shaking our boat, so that we would be scared of falling into the water.
On day two my wife and I took a tour to visit the Altiplano. The tour started a little boring, when we visited a few empty villages nearby which were all pretty much the same. Empty with very little people.
