Yeah, I think there might be a song in there....
I have some ideas for alternatives, if you're interested:
I'm always the bad guy,
But I don't really mean it,
I'm always the bad guy,
At least that's how they see it.
I always wonder who "they" are in phrases like this. Would it work to say, "At least that's how some see it"?
I terrorize without realising,
'Cos that's just who I am.
I cynicise and try to poison
every woman and man.
The rhythm of your last line doesn't fit for me. You might use "Every woman, every man". ??
I like to think I'm thoughtful,
But all those thoughts are sinister.
I'm trying to keep a handle,
But my skin's starting to blister.
The last line feels a little like it might have been a compromise in order to find something to rhyme with sinister. Maybe? Sinister is hard to rhyme. Some alternative words that might provide inspiration are: vinegar, minister, inquisitor, administer, finisher, insecure, listener, prisoner, mimicker. If it already says exactly what you want, of course, just ignore this.
The section you have labeled "chorus?" works for me as a chorus. I might change it a little to get rid of the "They're not happy". What do you think of combining the short verses you have and make half as many verses twice as long, and put the choruses in between? Maybe two verses before the first chorus. Then you might end up with something like:
I'm always the bad guy, But I don't really mean it,
I'm always the bad guy, At least that's how they see it.
I terrorize without realising, 'Cos that's just who I am.
I cynicise and try to poison every woman and man.
I'll pulverize all your joys, And I don't give a damn!
I'll lock your eyes whilst telling lies, I'm just that kind of man!
I don't pay enough attention, I do not have the will.
I don't think you're worth a mention, I do not like to spill.
I'm not happy you're not happy
We're not happy, no one's happy
I'm not happy you're not happy
We're not happy, no one's happy
I get all the blame.
I like to think I'm thoughtful, But all those thoughts are sinister.
I'm trying to keep a handle, But my skin's starting to blister.
I like to think I'm considerate, But I guess that must be lies.
I'm trying to keep learning, But my actions never wize.
I'm not happy you're not happy
We're not happy, no one's happy
I'm not happy you're not happy
We're not happy, no one's happy
I get all the blame.
Bridge
Falling to pieces...
The framework around us;
Used to stand strong like steel,
Now blows away like powder.
I'm not happy you're not happy
We're not happy, no one's happy
I'm not happy you're not happy
We're not happy, no one's happy
I get all the blame.
Anyway, just a few ideas that may or may not strike a chord with you. Feel free, of course, to ditch the lot or use anything that appeals to you.
