From the data you provide, this doesn't sound like it backfired at all.
In a difficult situation, you're the only one who did the right thing and it led to nothing. This says more about others than it says about you.
You boss got mad, yelled at you, and got fired. That's his problem, not yours. Others suffered or got fired and work wasn't finished. Again, their problem, not yours.
I think you should hold your head high and be proud. You pushed the envelope and challenged others, knowing full well that they might resist. The resulting negativity had nothing to do with your efforts and everything to do things being fucked up long before you got there. Don't let the illogical actions of others upset you, don't be depressed, and most of all, don't hesitate to continue to be proactive. The rewards may seem elusive, but believe me, you will find them.
