lie awake at night

A betrayal or a good decision?
I am currently playing an internet MMORPG game,
I like the game, coz it give me chances to talk wif lotsa people from different country.
I'd been joining an Italians' guild ( guild = tribe),
Its a nice guild as everybody help each other,
support each other.
And they gave me a higher position in guild,
which is next to the guild founder,
i in charge of all member other than Italians.
I can rank, i can kick, and i can decide to build wat building,
easy to say: i got authority.
But, it was later. I decided to leave the guild.
Leave,
becoz i found a better guild,
becoz i can understand their chatting in Italian,
becoz i need to grow at faster rate,
Becoz the guild is not suitable for me anymore.
I need a better guild!
The next morning i left the guild,
i got a lotsa personal message,
some wish me good luck,
but some said dissappointed wif me...
expecially those wif higher position in guild,
they said i m selfish, i leave everything behind after i found it no use to me anymore.
some even put me in ignor list....

So, tell me....
wat would u do if u were in my shoes?
will u leave the guild, or u will stay?

If we take this as a company,
u work in a company and then u get a better offer from another company,
will u quit the job?
If this is wat i will face in the future, i dun wan it to....
getting a better job= betrayal?
i admit tat i enjoyed a lot when i was in tat guild.
but, everyone have to look forward, am i right?
