OMG i need help!!

i seriously need help!
all you have to do is to read my post and tag at my tag box.

this is the story.....
Today was rDNA lesson.
and facilitator is sharing of some things or scope we might be in in future
he says ertain people are able to kill cancer cell in their body.
and if we are able to produce or to know what kills cancer cell, we are going to rich and hero.
guess what i replied?
i said : "Then this world is going to be crowded"
Am i seriously wrong?
or am i right ?
or i'm not in right or wrong?

what i felt is that...
some people are mended to go off, the one up there decide
so if some one is go come out with something that can kill cancer cell,
doesn't it mean that more people will be living in this world,
no people will die from cancer anymore,
this world gets crowded,
resources are depleting,
more pollution to the environment,
Earth is going to break down earlier?

I asked my mother, whether am i wrong to say such thing
she say i'm not wrong, i think in different way,
some people think it in a way which should save as many people as possible
but what i see is the negative outcome of saving people
She say i'm not wrong, not right, but cold-blooded.
OMG. am i really cold-blooded?

To me, it's like, if you save, one day everybody might die together.
when it's time to go, just leave peacefully
that is what i think
you all watch "i am legend" before?
will the outcome be like tat?
where some scientist says that certain thing can make people immune to cancer
but what is the outcome?
Creation of new diesease!

What do you people think?
if i was you, what will you do?

If i'm going to come out with such thing, i will let the government decide what to do
to give the cure to people who need it or to keep it a secret.
Nobody can predict what will happen next.
Maybe those tat are below 30 should take the cure?
it will be unfair. Yeah.
The cure can't be expensive, can't be selfish, can't have negative outcome.
so many thing to think of!
Does scientist ever think of all these?
i wonder.... or do they just want to become rich?
or want to save as many people as possible?
or to become well-known?

haha. some thoughts!
Wondering what others think
Andrew Toh says i'm wrong
Sis Tenna says i'm wrong
Mother say i'm neither right nor wrong
