@bananarepublic94 my analogy explained in short - what is a common trait of a wife-beater and smurffer in Apex = willingness and excitement/pleasure from dominating a weaker opponent.
Hope that makes sense to you now when translated.
As for SBMM and K/D ratio I would suggest you to read on it a bit a more and actually look at the facts e.g. take into account that the best player say in CS go in a recent tournament in Sweden achieved K/D ratio of 1.5 something something which is viewed as godlike...now think about yours 2.7...
My K/D started at 0.4 and now is at most 0.7 and I just reached Diamond 4 without too much hustle especially when playing on NA server, EU was/is a bit harder no doubt. K/D is not something that indicates how good you are as a player nor how successful are you in ranked mode because you can have a low k/d game and still gain RP and vice versa.
Again do some more detailed analysis, complain a bit less, think about your values and what harm are you doing when smurffing to the community, less skilled players and come again.
