Answer:

You are a match -

My body is thin and frail:

Matches are thin. Wooden matches are easy to snap, paper matches are even easier to bend.

Scratching my head can kill me:

When a match is scratched (on the striker for a safety match or on any dry frictional surface for an old-fashioned light-anywhere match) it burns, after which it is 'dead' - i.e can't be lit again.

When abused, I can also kill you:

We are all taught as children how it is dangerous "to play with matches". Fires can kill...

Usually, I'm helpful:

Of course - helpful for lighting a useful fire, or a cancer stick etc...

Will this also qualify as an answer?

Pencil

Scratching head can kill me

Sharpening a pencil rescues it length and it becomes useless after a while i.e. dead ... Also a dull pencil is of no use till sharpened again

Abuse

Poking the pencil in wrong place can lead to death

  • Good lateral thinking :) Could do with some beefing out like the other answer, though. – Dewi Morgan Feb 19 '15 at 07:25

    @dewi added explanation ... @ others I know you are protective of the community, but please don't go down voting because you don't agree ...at least leave a comment to why you down vote – user70926 Feb 19 '15 at 07:29

    Strongly agree - commentless downvoting is poor form. – Dewi Morgan Feb 19 '15 at 08:34
  • Very creative answer, and it does also seem to meet the riddle's requirements. However, death by pencil seems to be more unlikely, so I wouldn't say it is the best answer, but I'm impressed regardless. Your subject seems to be a fine idea for a riddle. +1 Regarding downvotes, I have sympathy. You should see the the downvotes on a couple of my weaker riddles. – Michael Rize Feb 19 '15 at 08:54

    "death by pencil seems to be more unlikely" - I guess you didn't see that scene in The Dark Knight where the Joker makes a pencil disappear through a henchmans eye and into his brain ... :) – Mashton Feb 19 '15 at 10:27

    One could also argue that a person in power could abuse their power using a pencil and call for the execution of innocents/you? – Elias Feb 19 '15 at 14:44
  • The "abuse" answer could be ingesting lead, even though pencil leads aren't really made of lead any more... – Lightness Races in Orbit Feb 19 '15 at 23:21

This is my first guess at the answer

Mercury Thermometer

My body is thin and frail:

Glass body is very fragile to being broken from children

Scratching my head can kill me:

Has a head that if scrated would break the glass making it no longer work properly

When abused, I can also kill you:

Mercury poisoning!

Usually, I'm helpful:

Taking temperature for everyone

My first thought was that you are a:

Video tape

My body is thin and frail:

The tape is very thin.

Scratching my head can kill me:

If you scratch the head in the video player, it can rip the tape.

When abused, I can also kill you:

You could probably pull the tape out and strangle yourself with it if you were really unlucky...

Usually, I'm helpful:

At keeping kids entertained.

I admit that my answer works best for the head-scratching part, the rest of it is a little bit stretched...

My first thought was

A spider

I am thin and frail.

Most certainly.

Scratching my head can kill me.

From what I gather, if you stroke a spider's head, they "go bald". I presume enough of this can kill them.

When abused, I can also kill you.

Spiders can be deadly.

Usually, I'm helpful.

House spiders are especially helpful at killing house flies.
