compare and contrast the characters of duke senior and duke frederick

Both these guys are brothers yet totally different in personality. Frederick is the younger of the two. He is jealous of Senior's wealth and status. He weasels his way into power banishing his older brother and plundering anybody that supported him. Duke Senior sets himself up quite nicely in the forest of Arden and Frederick can't stand this. He wants Senior to suffer and frolicking in the forest isn;t suffering. So, here we have two very different outlooks on life. One is content and the other is never content. THere is a simple virtue in Senior that allows him to appreciate things other than power and money. Frederick is consumed by power, money and control.
