Is it odd or weird to feel bad for a stranger?

I drive for Lyft on the weekends and I come across all kinds of people. Usually I stay quiet and get them to their destination. I’ll ask if they’re comfortable. What radio station they would prefer etc but that’s it but earlier today, this specific rider, really young girl, said she was twenty three but looked younger than that, got in my car. I picked her up and she had two purses and a book bag which seemed filled. She got in the car, spoke really softly and got on her phone but what I noticed when she got in was that she had a black eye. Even with the face mask? You could see it. Which is when I started to make conversation. I don’t normally do that. I asked her if she lived where I picked her up at or if her destination was her actual home, she said her destination was where she lived. I noticed a toothbrush on the side of her book bag so it was as though she stayed a few nights out at a significant others house and after seeing her black eye I asked if she was dating anyone and she said she had a boyfriend but she wasn’t too enthusiastic when saying it. When I asked if he treats her right, she hesitated to answer. As if she was unsure what to say but eventually she did say “yes” but her yes just seemed so off and my mind just couldn’t forget about that black eye. I asked her age and she said twenty three and I was shocked because she looked at least, 15 or 16 years old. A real baby face and her being short didn’t help but twenty three is still rather young to be in a situation that I was assuming she was in at this point of the small conversation. She was so mild and soft spoken, seemed like that’s naturally how she is but at the same time it seemed she was fighting something mentally and emotionally and even as a stranger I really did wish I could help but I don’t even know if what I assumed was true or not though it seemed to be.
