Yes, the new health care law was made with good intentiions by the people in washington, but it is looked at as a real bad thing by all of the people in the US. This shows that you can be just trying to help but it may end up bad.
I think that when it comes to politics, bad outcomes can be justified with good intentions. I think that people will be willing to forgive if policies don't work if the politician had intended to make it work with good intentions. It's important to realize that ideas and plans don't always work.
The outcome is ultimately what matters, and even entering a situation with the best of intentions doesn't mean anything if the outcome is ultimately a failure This is especially true of politics, where a bad outcome can cause devastating consequences to the overall stability of a functioning society that the government is meant to uphold.
No, good intentions do not justify bad outcomes. Politicians are responsible for a huge number of citizens, and they are elected to get results, not to make excuses. If a bad outcome results because a well-intentioned politician was not skilled enough, it doesn't justify that politician's lack of success, and the politician will usually suffer for it in the polls.
No, I do not believe that bad outcomes can be justified with good intentions, in terms of politics, because it is the politicians job to have the good judgment to pass laws that lead to good outcomes. A person doesn't get to keep any other kind of job by having good intentions.
