Headspidered victim dying should let the spider instantly take over

[Nerkson]

So I checked the wiki and according to it:

>>> If you successfully implant yourself down a victim, then unless they get immediate surgery or are killed (the suicide command is disabled), you'll control of their body and live again.

So it seems the suicide command is automatically suppressed, which means the method of suicide people are talking about must be grinder/incinerator/other methods of immense damage quickly.
