Every human has free will, so behavior as an adult is based on choice, despite childhood experience
While childhood teaches us a lot about the basics of human relationships and skill-building, it is not an infallible determiner for how an adult will behave later in life. Life is not deterministic, and our choices are not pre-coded based on our childhood experiences. While, for example, someone who was abused as a child may be statistically more likely to abuse others as an adult, that is not 100% always the case. Plenty of people who suffered abuse are able to grow into healthy, functioning adults who actively make choices despite experiences in their youth, not because of them. A study done on people from infancy until the age of 32 found that only 10 percent of their academic performance could be attributed to their childhood home life; the other 90 percent came from later experiences, genetic factors, and sometimes just plain luck. A person’s childhood experiences may teach them meaningful lessons, for better or worse, but it does not impede someone’s ability to make autonomous choices about their behavior as an adult.
Adult behavior may not be completely deterministic based on childhood experiences, but it has been illustrated in research again and again how childhood experiences affect our relationships as adults. Children who have experienced severe trauma have been shown to experience difficulty attaching, committing, and maintaining healthy romantic relationships as adults.
