When should I delete a pointer?
Original source
only when 'new' keyword is used? or every time I declare a pointer?

if you don't use the "new" keyword (or call some function that does it for you), you should not delete the pointer. Generally, it's better to use smart pointers and avoid "new" as much as possible

So, doing something like this:
`std::list<Unit*> targets;`
Would not require to delete?

no, because you're not the one responsible for unit pointers. However, be very careful about storing entity references like that

no, it will not, your pointers will be dangling and there is nothing you can do about that
