A short paragraph

Hi guys, I am wondering if anyone have time to quickly skim through this paragraph and point out any grammar mistakes you find. I would really appreciate it, thanks.

This the 2nd paragraph of my Macbeth essay.

Light, the sole resistance against darkness, accompanies virtue throughout the play. Day, seen as a form of light, only makes appearances before and after the reign of Macbeth. Macbeth, by murdering the gracious Duncan, attracts an aura of evil around him and causes the banishment of the good, materialistically presented by day. Consequently, Lady Macbeth unknowingly has her wish of "never / shall sun that morrow see" (1.5.59-61), granted. Day does not reappear again until Malcolm, the princely representation of righteousness, marches back to Scotland to reclaim his title. Banquo and Fleance, angelical in character, are juxtaposed by their murderers to "some streaks of day" (3.3.7) that yet glimmers in the west. When Banquo is killed, the murderers ask who "strike out the light" (3.3.27)? Even though the murderer asks about the torch, his question, on a deeper level, binds light with virtuousness. Lady Macbeth provides another affinity between the two. She, in her last days, has "light by her continually" (5.1.25) so that she may attempt a desperate battle against her unguarded conscience, filled with the horrors of evil. She is in essence, trying to use the good to block the evil. Ironically, Macbeth, the personal embodiment of evil, is "aweary of the sun" (5.5.55). The sun, the source of all light, is the oppressor of Macbeth much like virtue is the oppressor of vice. Light, thus, can be seen as a faithful henchman to benevolence and frequently accompanies him in his travels throughout the play.
