Let me start off by saying that you actually do have my sympathy, not because of the unexpected emergency at bad timing, nor the unfriendly attitude your teammates gave you, but because you think exactly the same way as I used to.
Real life issues happen. Technical difficulties happen. The entire city can go blackout and you've done everything you can to no avail. For the longest time, I thought in cases where I'm not the root of the problem I shouldn't be held accountable.
It took me a while before I realize that thought is deceit, once I looked at things from 3rd person perspective. Say for example:
- five of you are buying a pack of five-bottled drinks, 5$ value, from a vending machine with no refund function
- all of you agreed to pay 1$ each
- the other four people inserted their coins
- unforeseenable incident happened and you weren't able to pay your share. It could be anything from a hole in your pocket to someone pointing a gun at you and threatening you to hand over all your $
- Insufficient fund paid so vending machine gave neither the pack nor $ back
In the end you're a victim. You lost your $ and it's not your fault. However, all of you promised to meet up and buy the drinks, but because one stranger was unable to pay up these ppl spent their time and effort (to get their hands on their $) yet didn't receive the deserved drink, and they have no reason to suffer because of a stranger's circumstance.
Generally ppl will forgive you. Your absence is justfied morally, but the action itself violates rules regardless and punishment will follow just like how a robber is punished for stealing drugs even if his intent is to save his dying parents.
Think of it this way: if someone breaks into my house with a knife while I'm gaming, am I going to abandon the game and run? Duh. My absence will make my team suffer, and I'm warned that I'll be punished after. Am I still going to run? Well I'm sorry, but I can't die before I lose my virginity. Because my reason of absense is relatively significant I decide to run, and only then should I consider running because punishment is nothing compared to what'll happen to me if I don't. This is what I meant by "nor do I see why you'd be concerned over the consequence of your action". If your reason to leave is just as significant, to the point where you feel comfortable saying "if that's what it takes then so be it", then you shouldn't be concerned over it.
