Kant is certainly not a bad philosopher. His positions on Ethics are reasonable and well justified. He discussed a physical teleology of morality terminating in God; so he is certainly congruent with theistic belief.
If you have not read his three critiques (Pure, Practical reason; Judgement). I’d reccomend these three as a good place to start if your looking into Kant.
He’s not my favorite philosopher; but he is certainly one you can’t ignore.
