We all know people have a tendency to deceive themselves into thinking they have (or do not have) a particular personality trait, desire, or whatnot. It's a simple self-defense mechanism that boosts confidence - after all, without confidence, we fall apart. Unfortunately, these deceptions are often formed with the purpose of covering up severe trauma in our pasts, and, even more unfortunately, they often guide us into the same pain and suffering as we experienced before, often entirely without our knowledge.
My question is this. If you had the potential to help someone who was unwittingly walking the path of self-destruction, would it be "okay" to do so, even if there was a risk of failure which could permanently ruin that person's life?
If you prefer a mathematical look... lets say you have a 90% chance of significantly improving that person's quality of life, versus a 10% chance of completely ruining them. Is it okay to risk helping them, when it's not you that assumes that risk, even if the benefits may outweigh those very risks? If so, what if we apply these numbers to assisting one-hundred such people? Is it really okay to "save" 90 people, while destroying 10?
Alternatively, lets say you were lying to yourself (and weren't aware of it), and this behavior was slowly dragging you down into the depths. Would you want someone to try to help you, even if there was a reasonable risk that it would permanently ruin your life instead of drastically improving it?
PS - Try to understand that the issue isn't whether or not the person would be willing to let someone help them if asked - it's whether or not even offering assistance is justifiable with such a high risk of failure, and failure having such dire concequences.
