Persecution of Hindus and ending it

I saw that some users have posted comments like persecution of Hindus happened bcz of their own karma ,
Persecution of any body by someone else is an conscious act , like someone slapped you without any apparent reason , now if you say that it is bcz of your own karma , that will imply that the other person has no free will , or freedom of karma , he is there just as an agent to fulfill ur karma’s , not as conscious individual , so it will go against the very law of freedom of karma , while that person has his own individuality and will suffer for his karma , just like you , he is just not an agent to give u reward of ur karma , he is starting his new karma by slapping you ,

similarly persecution of Hindu in hands of muslim was well planned and conscious act of muslims , with their own freedom of karma , for which they must suffer ,
