While street violence caused a lot of people to become disillusioned with democracy, a lot of that violence was orchestrated by the Nazis (and regular conservatives) in the first place.

Read about this dude (who was not a Nazi), it's a fascinating story about how he tried to play everyone, only to tell the wrong dirty joke to the EDIT: President's son and lose everything. I wish I knew what that joke was tbh.

Importantly:

Brüning banned the SA and the SS on 13 April 1932 on the grounds they were ones chiefly responsible for the wave of political violence afflicting Germany. Additionally, rumors had started that the SA men serving in the Grenzschutz forces were helping themselves to the weapons stored in the secret Grenzschutz arms depots, and had transferred them to their own arms depots. The SPD Prussian minister-president Otto Braun ordered a series of police raids on the SA, which confirmed that the rumors were true. For Brüning this was the final straw, and despite all of Schleicher's vehement protests and his argument that there was nothing wrong with the SA stealing Grenzschutz weapons under the grounds that they meant only to be used against the Communists, the SA was banned as a threat to public order. The banning of the SA and SS saw an immediate and huge drop in the amount of political violence in Germany.

On 15 June 1932, the new government lifted the ban on the SA and the SS, who were secretly encouraged to indulge in as much violence as possible. Schleicher wanted as much mayhem on the streets as possible, both to discredit democracy and to provide a pretext for the new authoritarian regime he was working to create.

So actually it was not the leftists who did most of this, although they did defend themselves. Murdering people was explicitly a Nazi tactic to make people support them by tiring of the violence.
