The childhood of a sociopath sucks on many levels (sorry, no other way to put it). A sociopath would likely come from a household that is dysfunctional on some level: with being abandoned or neglected by the father as the most common case. Sociopathy is highly hereditary and the odds of a sociopath having a sociopath for a parent are very high. Not being able to form social bonds naturally, a sociopathic child would likely be bullied at school. Sociopaths can't comprehend and are incapable of violence without a clear tangible purpose, so the reasons for them being bullied would completely escape them.
As sociopaths can't naturally form in their minds a cause and effect relationship between doing something that is perceived by others as bad and receiving a negative stimulus, they don't respond to punishment normally. Any punishment that they may receive is seen as an act of senseless aggression. And furthermore, as the person delivering the punishment would not see a normal emotional feedback, they are more likely to intensify punishment in hopes to incite this feedback. But a sociopath is simply incapable of such a feedback and this situation may well spiral out of control. And as the positive stimuli don't really work either, such a child is likely to get totally demotivated, leading to study problems and delinquency. Forcing such a child to apologize for something or demand remorse from him or her is also seen as an act of emotional violence.
Having essentially the same emotional needs, dealing with all of this may be very hard and consequently sociopaths are suicidal and are very likely to inflict some form of self harm. Such a child is likely to adopt very early a mindset of "the whole world is against me" and will be very hesitant to ask anyone for help and always try to rely only on him or herself. This in turn may lead to petty crimes as doing so may seem as the only reasonable way of getting something they may need. A sociopath will not commit crime or cause any physical or emotional harm for fun.
Well, if a sociopath reaches adulthood alive and without a criminal record, it may become a whole different story. Though carrying a massive baggage of childhood trauma, a sociopath is likely to have a set of natural traits to be successful in life. By adulthood, a sociopath may have acquired emotional intelligence/people skills on an unparallelled level. This manifests in charisma and an ability to understand emotions and motivations of others. The analytical and decision making processes for a sociopath are largely unaffected by emotions, allowing to make objective risk assessments and decisions even in the situations that would be very stressful for other people. And there are many jobs out there where these capabilities are key.
As for the personal life of an adult sociopath, it is likely to still be pretty miserable. I discuss the reasons for this here. My personal way of dealing with this generally is honesty and transparency. As sociopathy actually is a medical condition with clear biological causes, I would tell those, who may be affected by my condition, about what my condition is, what it means, how to treat me in different situations, what to expect and, more importantly, what to not expect of me in different scenarios. I know, this approach is not for everyone with this condition. As for the success rate of people actually knowingly accepting me, it is fairly good at around 25%. On the other hand, I clearly understand, that being close to me may weigh hard on people, so I try to accommodate to the extent possible. But acting in an open manner has been generally worthwhile for me. At least I have the peace of mind, if not all of the relationships that I wanted.
