CMV: Plot involving Squidward is usually ill-conceived

Yes, there are a few times where the writers of the show have given the audience reasonable reason to take side with SpongeBob; but, for the most part, Squidward is unfairly vilified.  This especially happens when he gets upset over SpongeBob's shenanigans that disrupt or destroy his hobbies or even basic functions such as sleeping. 
 
Take episode 15 of season 1 - "Jellyfish Jam" for example: SpongeBob decides to take in a jellyfish as a pet and looses control of the situation.  Even after SpongeBob is advised by Squidward that taking a in wild animal as a pet is not a good idea; he does not listen and predictably, Squidward pays for it.  The music from SpongeBob's house plays for so long and so loud, that it completely prevents Squidward from being able to sleep.  Now, instead of making the audience sympathize with him when he becomes understandably upset, he is vilified to the tune of him being attacked by the jellyfish that SpongeBob no longer has control over.  Worse yet, the audience is, instead, lead to sympathize with SpongeBob.

It's not as simple as Squidward gets attacked->bad things happen to Squidward--> Squidward is the bad guy.

Rather, Squidward is the normal guy to which bad things happen for no reason. 

Good things don't always happen to good people in spongebob, and bad things don't always happen to bad people. Mr. Krabs is just as evil or worse than Plankton, but Mr. Krabs tends to get what he wants more often than Plankton. Patrick is a loser and drain to society, yet he's one of the happiest people in town. 

The central theme of Squidward's existence is that he lost control of his own life. He has to deal with the stupidity that Mr. Krabs throws at him. He has to sit and deal with Spongebob ruining the small parts of his life where he has autonomy and freedom to express himself. He gets hurt, blown up, and has mental breakdowns in half the episodes. It's almost always clear that he doesn't deserve what's happening to him-in his own words, "Why me?"
