With age, according to the idea, should come the mind, wisdom and the ability to see the essence of the problem and solve it. And if to you with age came the desire to kill - unfortunately, nothing came to you, so you remained an evil minor dwarf.
It’s not mine, but I’ll put my 5 cops in.
We have - a bunch of adulterated (or initially wild, born on will) aggressive dogs. Who at least scared or even bitten your mother/wife/child/you.
The essence of the problem is this particular room. here and now. Abstract reasoning - what to do so that such aggressive clusters do not exist - is not relevant at this time.
The solution to this problem is: I am eliminating. It can be handed over to the shelter for distribution to heart-hearted miserables. You really think you are an adult animal, accustomed to life on the street. Will it be permitted to live in the house? Well, if he just escapes into the usual habitat, and may bite the "home".
So - sanitation, if it is possible - the forces of special bodies to control this fauna, well, and if there are no such or they do not want to move or fear to connect with the dumb animal defenders - with their own forces.
No vivid emotions, no sadistic joy - naked calculation. Take care of the safety of your loved ones and yours. And love for people, at least for family.
