Warning: I'm feeling philosophical.
Unfortunately, some people don't understand the difference between motivation and technique.
It's related to the 'good intentions leading to hell' fallacy; both the intended idea and the saying being different fallacies.
First; good intentions never lead to hell. Good intentions combined with *bad ideas can lead to bad intentions and thus hell, if one starts blaming others.
Actually, that explains both fallacies.
There is a tendency for a person to think their intentions somehow justify their actions; for example, in a recent forum interaction (On another forum) I attempted to encourage responses to my post in a way that, it was explained to me, strongly resembled nagging - Or possibly even whining. While this was not my intention, intention is only part of an interaction. The actual technique or pattern used is the other part and unfortunately, I chose a bad one. When this was pointed out (In a PM), my first reaction was anger - 'I have intended no such thing, therefore I have done no such thing!' was essentially my first reaction.
However, I had - To explain, it does not matter to certain parts of a situation such as, if you wave your fist in the air, not intending to hit anyone, and hit someone, you have still hit someone. Furthermore, and most people know this, if you don't apologize, there's not much difference than if you had intended to punch them.
While my actions were not hurtfull in near the same way, they still resulted in damage, even if temporary, to my relationships on that forum. And both situations are the result of bad technique; most people would only accidently hit someone with their fist if they are unaware of that person. In a similar manner, I was insufficiently aware of a social convention and thus precipitated an accident.
This came about because of a lack of understanding on my part; I have a lack of natural talent for social interaction and have had to train that ability.
Similarly, a person may engage in activities which they are convinced are beneficial for another person, but which use either a bad technique or pattern or which are wrong for the person and/or situation.
However, it is my firm conviction that the same action done with good intentions will always come to a better result than the same action done with bad intentions.
