Does every thought we get contribute to our Karma?

Thank you for clear explanation.

Yes it does. in fact thought behind action plays more important role. eg Swami quotes is , you are walking road side, somebody pushes you from behind. you fall and get hurt. but when you look back, you see that he has pushed you to save you from speeding bus. even though pushing you may look like it will incur Papa, it is punya due to thought and attitude
