Sometimes when we humans are crushed by sinners, In the seek of justice! if revenge is the only option we choose then we also become sinners..... Then other than regretting there is no emotion left, and you know "Regret is the most strong but painful emotion in this world......."
Don't you think love and Regrets go hand by hand! you choose either to love or to Regret........
sometimes loving someone becomes our regret and sometimes not confessing to someone become our Regret.....
if Regret is confirmed than choose the path that you want, at least in this way you have to regret less...
