Hello psynymph
Yes, I do believe that greed and possessiveness are two different things.
To myself, greed is a state of always wanting more; no matter what that ‘more’ may be.
Possessiveness is a state of wanting to hold on to what you have. It’s a state of of believing in the ‘MINE” mentality. Everything is mine…mine…mine.
Technically, neither of these are really all that dangerous; it’s only when they are used to harm others that this becomes a problem.
Greed; constantly wanting more can cause a person to ignore and not appreciate what they do have.
Possessiveness is not overly a bad thing; it’s only when it becomes obsession that things can become dangerous in a sense.
I wish you the best
