Yugas and Good Vs Evil

A very nice observation by Sri Sukhi Sivam. During TredaYuga - the Good (Rama) and Evil (Ravana) were completely disconnected - not belong to one family. During Dwapara Yuga - the Good (Pandavas) and Evil (Duriyodan) belonged to the same family. During Kali Yuga - Good and Evil are in the same person - One time all of us Good and another time we become Evil.
So true...
