Yes. It was a bad play. You seem to have the bankroll for it, no reason for scared money plays.
I asked a question about how many players you wanted in with AA

I was feeling bad after losing 2 monster pots with AA, gettiing it all-in 3 way and 4 way. It was the right move, and I'd do it again. As a matter of fact, after reading responses (and the math), I like your situation even better. Yes, even though you lost.
There are very few reasons, and they are so ridiculously unlikely to happen to you (or I), that it doesn't bear much consideration unless you are in those circumstances:
- tourney on the bubble with all places paying the same, and multiple others already all-in
- Some kind of prize (tv show) for highest finishing chipstack, that you have already locked up can fold your way into an even bigger prize
- A really OMC (Old Man Coffee), a guy who arrived early with a single buy-in, planning to spend many hours in the card room (or walking around), unwilling to risk going broke early and not having money to play later.
Cash game in a local room, with a solid bankroll? No excuses for not shipping it preflop.
