in the torah it is written that any one who tries to turn a person away from worshiping one God, must be executed ,

deut 13

But that prophet or that dreamer of dreams shall be put to death, because he has spoken in order to turn you away from the Lord your God, who brought you out of the land of Egypt and redeemed you from the house of bondage, to entice you from the way in which the Lord your God commanded you to walk.

“If your brother, the son of your mother, your son or your daughter, the wife [c]of your bosom, or your friend who is as your own soul, secretly entices you, saying, ‘Let us go and serve other gods,’ which you have not known, neither you nor your fathers, 7 of the gods of the people which are all around you, near to you or far off from you, from one end of the earth to the other end of the earth, 8 you shall not [d]consent to him or listen to him, nor shall your eye pity him, nor shall you spare him or conceal him; 9 but you shall surely kill him; your hand shall be first against him to put him to death, and afterward the hand of all the people. 10 And you shall stone him with stones until he dies, because he sought to entice you away from the Lord your God, who brought you out of the land of Egypt, from the house of bondage.

my question is about pagan religions. in pagan religions was it okay to choose whatever god you wanted to worship ?

thank you.
