Therein lies a paradox .. if its been happy living in a symbiotic relationship with hosts for all that long, why does it still posses the ability to kill itself off in this manner ?

Again there is no paradox here.
You can safely assume that a bad mutation took place... and bacteria with this will not survive.
But, if a good mutation takes place - for example, bacteria multiplies a bit more but doesn't kill the host BEFORE it manages to jump to another one- then this strain will survive (read: that DNA will survive).
No paradox at all.
