"Oh, that this too, too sullied flesh would melt, Thaw, and resolve itself into a dew, Or that the Everlasting had not fixed His canon 'gainst self-slaughter! O God, God!..."
Act 1 Scene 2
"...Yea, and perhaps Out of my weakness and my melancholy, As he is very potent with such spirits, Abuses me to damn me. I’ll have grounds More relative than this. The play’s the thing Wherein I’ll catch the conscience of the king."
Act 2 Scene 2
Act 3 Scene 1
"To be, or not to be? That is the question— Whether ’tis nobler in the mind to suffer The slings and arrows of outrageous fortune, Or to take arms against a sea of troubles, And, by opposing, end them? To die, to sleep—No more—and by a sleep to say we end The heartache and the thousand natural shocks That flesh is heir to—’tis a consummation..."
This line really shows how Hamlet feels on the inside. This is right after his mother and uncle walk out of the room. he talks about how life sucks basically. He also says he can't kill himself because that would send hi straight to hell.
In this quote Hamlet is being mischievous by thinking about getting the actors to basically make a play of his father's murder to see if how Claudius reacts.
He's saying to be alive or dead. what's the point of fortune when you are internally suffering? He compares sleep to death, but you can wake up from sleeping. when we sleep problems of the real world leaves us.
