Why not hurl the Parker solar probe into the sun at the end of it's mission instead of letting crash into Venus?

I know at the end of the mission, the solar probe is supposed to be crashed into Venus (or so I think). So, if it's just going to be trashed, why not hurl it directly into the sun and continually take measurements and send data so as to see how close to the sun the probe can actually get before all gadgets stop working; it might also give extra data being closer than the other flybys.

I'm a chemist but not an astrophysicist, so I do have much education in this area.

In terms of the amount of fuel required to get somewhere, the sun is actually the hardest thing to reach in the solar system. The Earth is orbiting the sun at about 30 km/s, and given the size of the sun in comparison to the distances involved you would have to cancel essentially all of that velocity in order to hit the sun. Reaching other planets is much simpler, because once you've escaped Earth's gravity it takes comparatively minor amounts of fuel to reach any other planet since they're all orbiting in the same plane as the Earth.

You've probably heard that the Parker Solar Probe is the closest object humanity has been able to send something to the sun, and also the fastest object humanity has ever produced? If it were feasible to send probes closer to the sun for scientific purposes it would have already been done. Even the PSP had to use multiple gravity assists from Venus in order to get as close as it did. In order to get substantially closer, close enough to be truly within the sun, it would need to cancel the majority of it's current velocity, which simply isn't feasible. The probe at this stage only has a minor amount of propellant intended to desaturate the gyroscopes, so that it is able to properly aim the heat shield at the sun during perihelion. Certainly not enough to meaningfully change it's orbital velocity.
