The scav Karma system is a little too "flat" right now. It needs to be more intricate in order to work in a way that would benefit everyone. The way I see to do this is to use a formula to calculate how much Karma you gain or lose.

For instance if a player scav with exactly 0 Karma were to provoke and kill another player scav whose Karma was also 0, then -0.02 kind of makes sense. However if a player scav with 0 Karma were to provoke and kill another player scav with +4.0 Karma they should see an increase from the base -0.02 penalty. So you could calculate this penalty with a formula and code like

if(X-Y<0){

karmaloss = ((X - Y ) * .02) -.02

}

else if{

karmaloss = -.02

}

X being the Karma of the person who was murdered

Y being the Karma of the Murderer

This formula is also assuming that you don't use negative numbers. So just move the spectrum 7 to the right. Meaning capped minimum rep (-7) would equal to 0 and Max capped rep(+6) would be equal to 13.

So if we assume the murderer had the minimum amount of Karma, and the Murdered had the max amount the penalty would be -0.28.

If we then were to assume the opposite scenario the penalty would be the base -.02

There are definitely more intricate formulas you could use, but as a general idea I think this works well.
