Goblins aren't meant to be empathized with. They weren't designed to be a playable, relatable race - and they still haven't been given that status. Drow were.
expect goblins are playable in 5e they have character race and stats skill guides to build them and classes to recommend with them if you dont empathized with them then that is personal people enjoy Drow beacuse they are evil elves people enjoy goblins because they are evil gnomes if you dont like them then dont play them but many people do The core of D&D is storytelling. You and your friends tell a story together, guiding your heroes through quests for treasure, battles with deadly foes, daring rescues, courtly intrigue, and much more. All the more reason to add them whether you love or hate them, everyone reacts strongly to well developed goblins. You hate them? Great they are there to exterminate. You love them? Great they are their to play as and recruit to travel with they are already within the game with likable personality's so why not as a choice to be one
