Is it fine to have high bad cholesterol if one has high good cholesterol?

Depends on a lot: 1st, it depends how high. If HDL is over 85, then yes, LDL can be very high - for most people. 2nd, what other risk factors do you have? With high bp, smoking, diabetes and obesity, then the hdl-to-ldl ratio should be better because risk is so much higher. See a lipid specialist and consider a 'fractionated lipid panel' to help determine risk.
