My thought on this is that its not bad gambling for just a gambler but for a religious person or better still a clergyman I think it's bad to do so basically it's based on their beliefs and religious and mostly it's against their faith, so it's not advisable for them to gamble cause it spoils their reputation. But in the other way round I think have come across some clergymen that gambles but I really don't have a close reasons of why they do so but I feel everyone in life have flaws and they would always fall for something so balancing believes and religion to gambling can be very tempting.
Yes when faith and religion are combined with gambling it can seem tempting to many because they can easily expect to gain something. But religion and faith usually try to show people a path that leads to confidence good decision making and conditional happiness. For this reason the relationship between religion and gambling is usually negative, because it is not conducive to a normal and stable lifestyle for people.
