Hm. Well I just went back and looked at your last post on the topic and I think the reason you got different responses is because you asked a different question.
Your first question was (paraphrased): Things are tough at my company and I'm being asked to fill in doing things I hate, and should I tough it out? To that question, my response is: There's no harm in looking for something else if you're unhappy where you are, but don't burn any bridges at your current job because with the economy the way it is now, you never know if you'll be able to find something. Right now I do think whatever your current job is, you kinda have to suck up the extra work load until and unless you have a solid alternative plan. Otherwise you might find yourself out of work and not able to find something else.
Your question above was (paraphrased): I'm concerned about the future of my company, and I have another opportunity, and am I a bad person for wanting to switch jobs? And my response to that is: You don't owe your current company any loyalty above and beyond doing the best possible job you can for them when you're there. But if you can find a better, more stable opportunity elsewhere, then you shouldn't feel guilty about taking it and moving on.
So really you're getting the same answer in both threads - just from different perspectives because of the way the question was phrased: Don't jump ship just because you're being asked to do extra work that you hate, but don't feel like you owe the company your first born just because they employ you either. Take care of yourself first - whether that means being cautious and holding on to the position you have or moving to something better.
