Let me explain the reason for that. Imagine you CAN run programs by just
 writing their names, when you are in the directory they are in.
No imagine you have a directory
Suppose, you do:

cd /some/path/to/a/directory/writable/for/another/user

KABOOM, you removed all your files!
How could it happen?
An evil user created a file named "ls" in
and put the following code there:

rm -Rf /

Now you should be able to understand the reason behind that. That's why
you SHOULDN'T put . into your $PATH
