I urgently need you to revise these sentences, too. I made some variations, but I have to be sure that everything is OK. I don't know if sentence 1 can make sense.

1) Two philosophical positions, which remain unreconciled in Hamlet's monologue, are expressed in the first lines: one is the Stoic attitude of enduring life's evils and misfortune at all costs and to an end; the other is the belief that, man may end his life by suicide. As a matter of fact, Hamlet can put an end to his sorrows either by committing suicide or by killing Claudius. However, both passive and active resistance are bound to meet failure.
2) The medieval perspective, which considered death as a liberation from the prison of the body, is countered by the Renaissance one, which doubted (or was doubtful about) the existence of an afterlife.

1. No capital S on "stoic" -- http://www.answers.com/topic/stoic

You should clarify "and to an end" -- it's mystifying!

Sure! Here are the revised sentences with some minor changes for clarity:

1) In Hamlet's monologue, two philosophical positions that are left unresolved are expressed in the opening lines. The first position is the Stoic attitude of enduring life's evils and misfortunes no matter what, with the ultimate goal of reaching an end. The second is the belief that a person has the option to end their own life through suicide. Consequently, Hamlet faces the choice of either ending his sorrows by taking his own life or by killing Claudius. However, both passive resignation and active resistance are destined to fail.

2) The medieval belief that death is a means of liberation from the constraints of the physical body is contrasted with the Renaissance perspective, which casts doubt on the existence of an afterlife.
