It is said in Zohar and other sifrei Kabalah that our Aveiros create Shin Daleds and these are called mazikim. These mazikim are our own mazikim and they are the ones that cause us problems. Peopl ethink “Hashem did x to me” no, your own mazikim that you created did it to you!
This is a deep concept and an important one to know and understand. We punish ourselves with the averos we do.
