Cruel cruel world

Today we went to visit the S-21 and the Killing Fields of the Khmer Regime. S-21 is the centre where approximately 20000 "enemies"of the regime were tortured, interrogated and subsequently killed. Upon arrival to the centre, the building is unassuming as it used to be a high school. Only the barbed wire and iron corrugated fence belies the terrible acts committed within. Entering the compound and the first building, you encounter terrible rooms like the one shown here. These were the torture rooms and when the building was raided, they found corpses on these beds in various states of decay and evidence of the torture they had were evident.
I didn't want to take any pictures of those bodies and faces of victims because it didn't feel quite right to do so. I was pretty emotionally overwhelmed, I can't understand how people could do this to one another and even to little children as young as 3! They surely cannot be enemies of the state! In the next building, there were the cells where inmates were kept, I had to leave the room because it was very creepy, claustrophobic and I just had really bad vibes in the area (yes, it might be all psychological, but I really didn't feel comfortable). There were also hundreds upon hundreds of photos of the victims. There were accounts of people finding loved ones ' pictures on the walls after the centre became public. I cannot even imagine the feeling of finding out that your husband, mother, father, child suffered in this horrible place.
In the afternoon, we went to the Killing Fields (Cheong Ek) where the mass graves were found. There were ditches where the bodies were discovered and supposedly more are still buried there. You also came across pieces of clothing from these corpses which I found very grotesque and slightly disrespectful to the dead. You would hardly believe this pristine, quiet area hides so many tortured souls.
People can be so cruel to one another.
