Writing Feedback / Introduction/Thesis Help (good family = good future, bad family = bad future) [9]

Hi, I am new here, and forgive me if I post this in the wrong forum.
I'm doing an essay on how basically good family = good future, bad family = bad future. It's quite ambiguous but, it is the common theme in the two books I have read.

Here is my introduction and my biggest concern is the thesis, which should state the good/bad future statement. I am having trouble continuing with the essay because of the thesis. It's hard to write about something that I am still not sure of. So please help and thank you in advance.

In a world filled with wars, environmental disasters, and indiscriminate crime, it is a wonder how anyone can laugh, fall in love, and live life to its fullest. It seems as though at every turn, there is an obstacle after another. So, how is it possible to navigate through all of these horrors and love life? The key is a strong family. The family must be supportive, caring and understanding. Because it is this family, that allows us to successfully navigate through the horrors of life. However, not everyone is fortunate enough to be born into this kind of family. Instead, they have to search for an alternative, someone who may be able to replace this ideal family. In the novels book 1 and book 2, both antagonists share the same fate. Neither of them had a strong family, instead theirs were corrupt and slowly, the two boys ended up as rotten apples not falling too far from the tree. This is why we as social beings need a strong family, in order for us to not to fall into the depths of despair by repeating the wrongs of those who came before us but instead, to flourish and develop ourselves into the figures of society who may one day support the path our child choose to walk on.
