Which line below from act v, scene i, of twelfth night suggests that duke orsino considers olivia a heartless person? duke: why should i not, had i the heart to do it. like to the egyptian thief, at point of death, kill what i love; a savage jealousy that sometime savours nobly.—but hear me this: since you to non-regardance cast my faith, and that i partly know the instrument that screws me from my true place in your favour, live you the marble-breasted tyrant still; but this your minion, whom i know you love, and whom, by heaven i swear, i tender dearly, him will i tear out of that cruel eye where he sits crowned in his master's sprite.— come, boy, with me; my thoughts are ripe in mischief: i'll sacrifice the lamb that i do love, to spite a raven's heart within a dove.
