Being controlled by sin

If we look at the world from the point of view of a person there is distinct start (birth) and end point (death). However, when it comes to our sub-consciousness we only really begin to fully appreciate as we start to remember things. Over this age of development, children begin to learn to good from bad and start to define what they have done as either good or bad. 

Can a person ever not commit a sin in a lifetime. I am thinking no particularly commandments such as "Honour father" & mother and do not lie. So what happens next do we spend the rest of our live in remorse ? forget ? or forgiving/accepting ? 

Each action has different consequences in term of short term or long term benefits. For instance the acceptance might be a higher stance from a long term perspective. The person could be said to be lived and and learned.

Holding on to the wrong can be considered to create a fault line in the character. People who have committed the same sins will be able more easily identify those that have such faults. Using words as swords other people are actually able to use these fault line for control. 

I do not want to go through these methods as there already enough people out in the world trying to exploit people fault for control.

Who would want to rule over other 

- those that have sinned and cant forgive themselves

- those that desire is to control others (always a bad thing ???)

There are however strategies that can be employed to counteract the tactics of other 

- know thyself 

- observe surrounding 

- trust self 

- trust in beliefs
