So you wanna take revenge on BSF by killing your own citizens. That's pretty funny. By doing the that, in the end it'll be you who will pay the price anyway.
And why do you think we'd care if they are victimized?
Bangladeshi population would have also increased in the same time.
Anyway in the end it boils down to one thing which is, for each poor Indians in UK there are 3 rich ones, so it's UK which is getting profited not us. However same can't be said in case of Bangladesh.
Talking about money and all that is not really of my taste, being a Bengali bhadrolok that I am, but it's you who came up with Indians making UK a slum thingy.
