No, what kind of question is that?
- Who is the woman and why should I care?
- Why is she being "harassed"? How do I know that she's not being attacked for intentionally running a paedophile ring that resulted in the death of countless children?
Now answer this question honestly: are you only interested in "saving" the woman on the off-chance that she'll put out for you? Would you risk your life if the person being harassed were male? If you wouldn't, that makes you a
white knight.
It's easy to look at a situation and make assumptions, but how do you know that your act of "generosity" won't cause more problems for other people? For all you know, saving her life could have dire consequences. Refer to the
trolley problem; do you save 1 person or do you save 5 people? Do you push a corpulent person on the tracks to save everybody? There's no right answer, only speculations.
