Quote Analysis

Laertes, about to fight the third bout with the poisoned sword, hesitates privately, troubled by the dishonorable nature of what he is doing.

The aside reveals internal conflict in real time: 'almost 'gainst my conscience' admits doubt without quite committing to it. 'Almost' hedges—he's troubled but not enough to stop. This momentary flicker of moral awareness makes what follows worse; Laertes knows what he's doing is wrong but proceeds anyway, making him complicit rather than merely deceived.

Support a thesis that Shakespeare shows characters choosing corruption—Laertes's hesitation proves he recognizes the dishonor, so his decision to strike anyway reveals revenge overwhelming conscience, not ignorance excusing it.
