I have a hard time understanding the difference between aforethought and forethought. Based on this link from wikidiff, the difference is explained this way:
forethought is thought of, or planned, beforehand while aforethought is premeditated; planned ahead of time.
I fail to see any difference between "planned beforehand" and "planned ahead of time". I interpret these two statements as identical.

aforethought is a an adjective and restricted to a legal phrase "malice aforethought". If a person kills another person it may be a murder or a manslaughter. The difference is whether the person intended to kill or injure or not. This intention to do harm is called "malice aforethought"
Forethought (a noun) is just thinking about something in advance: planning or preparation
