Kant makes some good points and presents some foundations for our modern morals. He provides the foundations for "good for goodness sake" and the modern golden rule. He introduces the idea of treating people as ends rather than means. He describes the difference between rational beings versus animals.

While he is important in philosophical thought, Kant is also a disorganized and confusing writer. He has great ideas that are interesting to see as foundations of modern morals. However, they are not good for realistic applications because there are many exceptions, blind spots, and rules. Great to read to understand and see where our current morals come from (historical side), but not great if you're looking to gain separate insight.
