It emphasizes tension
In the passage, Death was personified to show how the old
man seems to have perceived his impending death despite not having seen nor
heard the presence of the murderer in the room. Death had the characteristics
of having the ability to stalk, to have a shadow and to envelop its victim. All
of which are humanistic attributes that death in its real sense could not
possibly enact. It creates the tension on the murder that is about to happen
and the thoughts of the murderer on his victim.
Based on the genre, (let’s take fantasy for example) you can get inspiration from fairytales, creatures, history, or your imagination. Mostly your imagination can help you with coming up with ideas :)
Simon and Piggy were not all that different. Simon was good and kind, but perhaps a little bit braver than Piggy. Piggy was timid, and vulnerable from years of torment and bullying, but somehow still a good person. Although the world around them seemed to be going mad, they both remained kind, whereas characters like Ralph and Jack added to the madness, and caused even more problems.
