Oh, well they just have to be bad then. I haven't actually killed myself with stickies in general (unless it was a mistake purely on my part, it usually doesn't involve others at all), Scottish Resistance would seem even easier to avoid killing yourself with considering it's really only useful for traps.
a Scottish resistance demo tried to kill me as a solly, he placed 2 or 3 stickies nearby where I was going towards him, he also had some behind him and I shot a rocket and he flew back right above the stickies behind him, detonated and killed himself.
It was pretty hilarious actually.
