pity, mercy, compassion
愍 centers on a heartfelt response to suffering: feeling pity, showing mercy, or acting with compassion toward someone in distress.
愍 combines 心 (heart) with 敃, which likely contributes the sound and may relate to effort or distress, together expressing a heart moved to pity or compassion.
The heart 心 under 敃 (a shape suggesting troubled effort) shows a heart stirred by another's hardship: pity and mercy arise.
For ビン, imagine a bin of donated goods given out of compassion: bin -> ビン, and your heart moves you to fill the bin for those in need.
