Polygamy, polyandry and monogamy occur in accordance with societal rules. These are customs and traditions. No karma is involved in any of these practices. At present Hindu society does not accept polygamy and polyandry and these practices have also been made illegal. Smriti texts also advise discarding of customs and traditions which arouse indignation.
However, discard the desire (kama) and material wealth (artha) if
contrary to Dharma; as also, any usage or custom or rules regarded as
source of Dharma if at any time they were to lead to unhappiness or
arouse people's indignation.
Manu Smriti 4.176
So can one (Hindu) marry more than one woman now?
The answer is yes if one has divorced prior to the second marriage. The answer is no if one wants to marry while one is still married. Any attempt to marry a second woman while one's wife is still around would attract legal penalties and the second marriage will not be legal.
As long as their is truce and the condition for such marriage is acceptable by both parties, and the subsequent others.
This choice is for the humans to make , we have that liberty, the modern society especially that of india is very punishing to those who believe in personal liberty, meanwhile these liberty are give to us by very gods and the chetna and budhhi that we have
As far as karma is considered,
A- NO, a bad karma would be if someone would be hurt by that said marraige, if there is agreed conscious couple marrying after taking the agreement of the other person, it is justified. The other parties do play a role in it.
Subhadra also had to be accepted by Draupadi .
So yes, it's acceptable, but norms in this yuga, especially of current society are not as moderate for those principles and the ruling govt often regulate private choices .
