Answer 3

Mercer gave you a great answer.  If you don't watch any show properly from the beginning, you won't be able to follow it most of the time.

SPOILERS

Dexter's mom was murdered in front of him and his brother when they were little kids.  The cop who found him adopted him and raised him not to kill people, even though he had serial killer tendencies.  Now, he only kills "bad people" - child molesters and others who deserve it.

Answer 4

He doesn't work for the FBI.  He's a forensic specialist for the Miami PD.  And he doesn't want to kill his sister - he spends a fair amount of time protecting her.  As he says, if he were capable of loving someone else then he would love her.

The show is available on DVD.  You should watch it in order to understand it.

Answer 5

He works as a blood splatter expert for the Miami PD.  He is not a cop but a specialist.  He does this work because it is something he is good at and it gives him access to police files and investigations.  He does not want to kill his sister in the series.  In the book he had a moment when he almost considered it.  However, he fought back that urge and did not do it.
