Does religion study will make kids a better person?

No. I think that kids who are raised to respect their elders, and to have responsibilities and to accept the consequences of their actions are better behaved than other kids. Most kidstoday, even those with strict religious upbringing are not made be responsible for their actions.

No, because the moral values are imposed. And the child has no choice here. The parents choose for him religion. The child can be strongly disagreed to study it. Or to deny the usual doctrine. So there is no garanty that the religious child is a good child. Or visa versa: the child without religious beliefs is not necessary worse.

I think "Better Bahaved" is not only from "emphasis in religion", but also it's from the other sources such as family background; eduction; environment etc. Religion might or might not affect children's behaviour. Some children is very intelligent now, they choose what they believe and the parents can not force them to believe on what they believe on their religion.

this is the diffrence between religious study and the study of morality. scenario: an 8 year old boy hits another boy for taking his toy religious way: "dont hit that kid because god is watching you and you dont want to go to hell do you?" moral way: "how do you think that kid felt when you hit him?" "sad/hurt" "do you like that feeling?" "no" "do you think its right to give that feeling to others?" "no" etc etc... so the moral way is justifying why while the religion way is through threats (hell) or through awe (heaven) also, since morality is older than religion, i conclude that religion does not make a kid a "better person"

Yes,i think so.People usually do things that he or she thinks right.And religion can be useful in some meanings.
