I think one leads to the other and though it might be the root cause, it doesn’t necessarily mean that, it is the worst and am speaking in terms of greed.

Greed isn’t any good attribute for anyone to let himself or herself be affected by, greed is that thing within you that doesn’t even allows you to recognize your wins. It pushes you to go for more and that often leads to doom. Now, it’s understandable that, greed could be the cause of addiction in the sense that, it keeps you closer to the game, every time you play, win or loss, you take a step closer, increasing your stakes, spending more and more time at the game and suddenly, you find yourself not being able to draw the lines for a limit.

Addiction however is more associated with a lack of control, an uncontrollable desire to gamble by all means and with what you don’t even have. That’s more terrible, it pushes you to take uncalculated risk which could obviously prove to be your doom.

While both might lead to the same fate, addiction is considerable a more dangerous habit to cultivate.
