Actually, no. If said person walked into the game after signing a waiver saying they would not blame the company for the injuries from stepping into the game - no the game is not at all responsible. Ever watched reality programming? Ever paid attention to humans?
As this is not a hard and fast rule in real life - why under creation would it be a hard and fast rule in gaming?
MMO reward systems work on the exact same systems that most successful reward systems work on. The same one GAMBLING works on. Systems that are designed to take every advantage of the human psyche possible in order to eek out an extra penny. (not that hard! We're animals!)
You realize an entire mathmatical school of thought, an entire science, exists to study the best ways to manipulate other people successfully to get what XXXX wants?
Casinos across the world are paying probably billions of dollars to the men and women of this science to program their machines' algorithms and tell them what color to put on their bath mats.
Every one of these games (and all of gambling - RNG- so every MMO ever as they all have tons of RNG) operate out of the basics of Operant Conditioning, pure Behavioral psychology 101 - Inconsistent reward system.
This reward system is the most addictive - most reinforcing - strongest driving - reward system that we humans respond to. And we all do it - in little and big ways. Not all of us are addicted to it. But its present in all of our lives. And its the inconsistent reward system.
Its not the system that rewards or punishes you based on a consistent measurement and standard. Its not the one that always gives the treat at the first, or third, or 10th time you give the right answer (or the punishment at the wrong answer). Its the one that gives out its rewards in a random-seeming way.
That is the reward system that the rat will kill itself on before stopping a behavior. That is the reward system of anything using any type of "random" reward system - RNG.
Not when you know for every 3rd dollar you spend you give five dollars. But because you know that sometimes it only takes that one dollar to win a million. Ok well maybe the 2nd... ok now the 3rd. Only the third one tonight. Only the third one this month...

That is how real life works. You're responding to that drive right now - in this forum. Playing WoW, or any other MMO. The RNG Inconsistent reward system has you.
Stop blaming the devs. That's not how real life works.
The person walking out of the gun store who kills a person three days later - the gun store is not held responsible (at least not in the US Where Blizz operates out of.).
The person who goes and blows his entire family's savings of 30 years at a casino over the course of a month - the casino is not responsible for the loss of that family's money. Its not even responsible for keeping out known gambling addicts from their facilities! ITS NOT EVEN ALLOWED TO KNOW!!
Because no - its the INDIVDIUALS fault and responsibility to control themselves.
Its your choice. No. No they aren't responsible because you can't stop playing a video game. Not at all.

Go take a Psychology 101 course and ask the professor about gambling and behavioral conditioning. Go search a wikki. Everyone. Please. At least know what you're falling for.
And if you realize you have an addiction; that you really can't stop - please get help. Its a video game. The devs are not responsible for anything at all in your life. Unless they are paying you a salary to play and you sign a contract agreeing to play for said salary.
You're the victim of an algorithm. The proprietary system that Blizz protects above all else. Every game does. That's the stuff of billions.
