They should give us the option to turn it off in the options menu.
that sounds like a good option.
As i understand it, the issue is not you seeing the killcam, it's when your victim sees your killcam and thus, your location. You turning off the killcam in your options is not going to effect your victims ability to use killcam. There is a server-side CVar that allows the disabling of killcams but this prevents the server from being ranked.
Not like you are ever going to read this but in case you do, the OP's main point was how they did not like seeing the kill-cam and having to see how unfairly he died, and not how everyone finds him if he is camping
it's damn annoying to see; I don't need to be reminded of how unfairly I died.
