To me it is a serious question as to what extent one should, having assiduously followed the advice of the Kalama Sutta and so determined for oneself that the Dhamma is efficacious and worthy of full devotion, just dive in, disregarding all external notions of truth and falsehood as hindrances to advancement, and practice, exclusively adopting the Dhamma itself as one's moral universe, examining the Dhamma itself according to its own exhortations and strictures. This is an idea I have been toying with recently: what have the Western notions of truth and falsehood, or perhaps better stated, the feverish promotion of the importance of truth and falsehood in the West ever done for me? The world is as full of lies as it ever was, and I am as helpless in their grip as anyone ever was - except for the escape the Dhamma offers. Bhikkhu Bodhi, if I recall correctly, has pointed out that the Kalama Sutta does *not* indicate that trust (we can also call it faith) is not required to follow the path: the Kalamas themselves were not followers of the Buddha at the time of its delivery, so the advice given to them is not the advice to be given to a follower of the Dhamma, one who has already accepted it into their heart. There is no hell waiting for one who does so, in my opinion: life can only get better.
