What are your thoughts on early voting? (please do not reference political parties or candidates)

My buddy's mom died a couple days ago. She had already mailed in her vote so come election Day I know at least 1 dead person who's vote will be counted. I realize she was alive when she cast the vote but not sure I like that it will be counted since she's technically not here when the election happens. Another draw back to mail in voting are the ballot box fires.
