I think....
for 1 and 2....
It depends on whether u think it is a sin or not.
If u think it's a sin and u still do it, it's a sin. If u think
it's not, then it's not.
Because I think sin is supposed to be relative, not absolute. It
depends on your understanding and ur belief. And this can vary from
person to person according to his religion, or his understanding of
his religion, or his moral values.
And I think God is Almighty and Ever Merciful. How can we commit a
sin if we sincerely do not know/ believe it is sinful/ wrong?
So I believe sin is relative.
Now, to answer the question for me personally, I
think....errr....no. As long as you are not doing the execution or
killing with hatred or revenge or other evil motivations. But
that's just me. Other people can think it's still sinful coz it
takes life away. Then it can be a sin for them.
