Claudius in Act 2

In act 2 Claudius sends Rosencrantz and Guildenstern to spy on Hamlet and see how he is doing because he is worried that Hamlet is out of control, drinking, gambling and what not. Claudius says  "Of Hamlet's transformation, so call it,/Sith nor th' exterior nor the inward man/ Resembles that it was. What it should be,/ More than his father's death, that thus hath put him/ So much from th' understanding of himself/ I cannot dream of. I entreat you both/ That, being of so young days brought up with him"(2.2.5-11). Claudius is trying to act like he cares about Hamlet, though he really does not. He is just acting all of this, because he wants the queen and everyone else to think that he cares so much about Hamlet and that he wants to be his new father. Though what he is really trying to do is cover himself and make sure that no one finds out that he is the man causing all the issues with Hamlet, because he killed Hamlets father. Claudius is trying to act like the resolution to the problem while he really the issue. This is all part of Claudius plan to take over and attain absolute power which he craves so much.
Also in act 2 the kings also says "Thou still hast been the father of good news." (2.2.45) This shows that the king is completely fakes, the king knows that he is bad news. King also says "Well, we shall sift him." (2.2.61) Though he is trying to make things better. He is sending Rosencrantz and Guildenstern as part of his play on Hamlet trying to make him fall for him. Though the king does not know that Hamlet spoke with the ghost, neither does he know that Hamlet has a play of his own coming.
