A connection between childhood trauma and high emotional intelligence is certainly possible to a certain extent. As much as childhood trauma may lead to high emotional intelligence, in a similar way the presence of a healthy environment may lead to high emotional intelligence as well.

In most cases, the impact of childhood trauma is not positive for the most part. A person may develop distrust, anxiety, depression or various other mental conditions because of the occurrence of such events. Even though this may lead to the effected person treating other with care but it is most likely that a person has not coped with their childhood trauma which just leads to them avoiding or being suspicious of everything. On the other side, if the affected person comes to trust another person, they might get attached to an unhealthy amount which might lead to that other person feeling weirded out as they might not be able to handle such a thing. But if the affected person works through their trauma whether it be with the help of a therapist, friends or by their own, this would lead to them developing healthy habits and a high emotional intelligence.

There are many ways in which childhood trauma can help a person as they might also develop instinctual emotions in an certain environment which leads to them being wary of their surroundings, although this is much more related to personal use. Hence the development of high emotional intelligence can certainly have a connection to childhood trauma.
