While narrating the strength of Vali, Sugreeva says
समुद्रात् पश्चिमात् पूर्वम् दक्षिणाद् अपि च उत्तरम् | क्रामति अनुदिते
सूर्ये वाली व्यपगत क्लमः || ४-११-४
"Before the dawn of sun Vali unweariedly strides from western ocean to eastern, and even from southern to northern for offering

"A regicide, a Brahman-cide, a cow-slayer, a thief, an inveterate
killer, an atheist, and an younger brother who marries before his
elder, all of them will go to hell.
We should also remember that following Vedic rituals is different from being strict follower of Vedic injuctions. For that mattter, the demons in the kingdom of demon king Ravana, who was embodiment of adharma, did follow Vedic rituals.
