Was this reasonable to do?

[FTK]

Some background info :

I play every evening in the PP 5$ buy in tournament. Lots of players (1500-2500) and i like the challenge.
I play always very tight and normally finish just in or just out of the money.

I wanted to try a different playing style and play much
more agressive in the start of the tournament. Just to
see if i can build a big stack early that would carry
me to the final table(where the real money is).

The first hand in the first tournament where i promised myself to loosen up this happens :

I'm on the button and get dealed AK suited.
Early player raises 100, everyone in front of
me folds. I make it 200 to go (seems loose enough
compared to how i normally play !).
Everyone else folds and the original raiser goes
all-in. I called and lost to KK.

My decision to call was based on the following
reasoning :

1. With his all-in its reasonable to put him
on KK or AA. --> Bad to very bad odds for me.

2. This early in a tournament everything is
possible. People raise with middle pairs all
the time in these tournaments. His hand
could therefore also be QQ-66 or AK-AJ
--> Reasonable odds for me.

3. If i loose now, no real harm done. I will
loose 5$ (no big deal for me). I prefer to
go out on the first hand than after 2 hours
of playing and just out of the money.

4. If I win this hand i'm in a good shape to
keep following the agressive style i wanted
to use this tournament. People see i do raise
with good cards and i'm not scared out of the
pot by an all-in.

4. If I fold now, i loose 20% of my starting chips.
Nothing lethal, but my table image will be broken
beyond repair. Everyone will think i tried to buy
the pot and folded to a reraise of someone who did
have good cards. It will take a long time before
I can start to be agressive again on this table.

My question is : Was this decision to call reasonable and
was my reasoning that made me call correct ?
