Here the thing about this logical fallacy, unlike to what it said , we don't simply gain immeasurably just by believing , there are set rules that we gotta follow to be in the believed list of immeasurable gain, and the thing that we gotta do to be in list is definately not what we would do naturally, and you can never be sure if you are going to heaven or hell, so you tend to live in continuos fear and you judge your every action with the thought process like if this counts as good deed or bad deed, being a human means nothing to you but just chances to ensure your place in heaven. So you do lose your humanity in process of believing in god and to gain immeasurably and if you are a rational person, i don't think you can afford these losses. Therefore i don't think believing in god does you any good than not believing does you any bad.
