Dear, turning a blind eye to the sad realities is never helpful. You must get out of that "hate-Pakistan" shell as it really do not make you look smart. I know it is difficult but still it is worth trying.
As for Bangladeshi, they are not killing Pakistan Sympathizers, rather they re killing those who are not comfortable with India. There is world of difference between these two even though if you and many fail to understand.
Anyway, the point i made initially was that it feel good to know that our military and security agencies are taken seriously in the region. As for being threat for the region, you only need to look at all your neighbours and see if you have any conflicts with them? This will really help you a lot, that is, IT YOU WANT THAT HELP in the first place.
